My father was a conjoined twin so I called his brother...
my uncle on my father's side.
But then they were surgically separated, so now he's my uncle once removed.
Master Therion thats absolutely hilarious
The police have been notified.
@@slappy8941 .He said removed, not destroyed.
L O L
Master Therion you’re a monster.
Sooo there's identical twins, fraternal twins, and everything that can go wrong in the formation of either.
Well no, it's not really going wrong if both the twins survive.
I aM it’s an anomaly
@@trenicejohnson15 So is our existence... But that doesn't mean anything went wrong.
No, there was a third distinct type: sesquizygotic.
@Steve Right. I looked that up and 1 twin has normal male parts and the other had both male and female parts since their mother's egg split weirdly. Identical twins whose genes got messed up 🤷
I have a cousin who has 2 uteruses which is rare, but what is even more rare is that she found out one day that the second one became functional (which is super rare 1 in 25,000) and she was carrying two babies that weren’t quite twins. They were conceived at different times but ended up being born together. I don’t know if u didn’t cover this because they aren’t quite twins or u just didn’t know about this, but it’s super cool!
One of my friends sister has two uteruses too. She has had children from both uteruses. 3 from one and 2 from the other. I was wondering if they were going to mention this condition too. Now I know there are at least two women with this. Strange though that it is all hush hush in the family, I think it is amazing.
I've read about this happening.
@@heatherburrillwell that's plentiful
That is so interesting! I think they are only considered twins by the fact that they are born at the same time. They are more like fraternal. Other than that, they are just regular siblings. Different egg and sperm, and most likely different conception times.
Rebecca Roberts on CZcams had 'super twins' - I wasn't quite catching the full name - the rare occurrence where a woman gets pregnant while already pregnant, so they were 3 weeks different in gestational age. They were the 14th recorded case of it happening. I was expecting this to get mentioned too! Rebecca's twins were born on the same day at 33 weeks 2 days, and 30 weeks 2 days from memory, oldest first thankfully, to save confusion about who was really the eldest!!
I remember hearing about a woman that had all kinds of legal problems because her children didn't share her DNA. They even had someone in the delivery room when the one child was born to be sure that she was actually the one giving birth.
I don't recall all the particulars now, but they did eventually realize that she was a chimera. I've sometimes wondered when a DNA test comes back negative and the mother insists that no one else could be the father if it's a matter of chimerism.
But they'd be a match showing he's an uncle right?
Had to do with a divorce and establishing custody. Her kids went into foster care. Her stbx and she must have had a last fling, because she got pregnant again, and the rest is history.
You're probably thinking of Lydia Fairchild. en.wikipedia.org/wiki/Lydia_Fairchild
@@lyrebird9749 yes, she's the one I was thinking of.
@mwenyamutale1513 hypothetically there is a way for the kid to not appear as the fathers
heteropaternal superfecundation chimera twin.
i.e. Susan and Bill have a 3way with John, and susan becomes pregnant with Bill and John's twins (Sam and Elliot)
the baby's do whatever happens with a chimera, in the mothers womb, swapping cells that will become gonads.
After Sam and Elliot are born and reach adult hood, they get married and have kids. because Sam has Elliots DNA, and Elliot has Sam's DNA, Sam's wife becomes pregnant with Elliot's Genetic kids and Elliots wife becoms pregnant with Sams genetic kids.
if the Susan is also a heteropaternal superfecundation chimera twin (ideally one with only one of her twin's ovaries), then its possible that a dna test might not even register Sam's kids as being closely related.
keep in mind, heteropaternal superfecundation is incredibly rare, at about 0.25% of twin births.
Chimeras are also rare, so the chances of this happening are rare.
"Sir, your son has your brother's DNA."
"It's because I'm a chimera, right? Right? Please tell me I'm right!"
Hahahahahhahahaha
I mean, you would know it if you were a chimera, because you wouldnt have a living brother. I wonder now though whether there are cases of triplets who got out as twins and one got absorbed by one of the twins or both.
@@xxMpEGxx No not necessarily. He mentioned that some live twins are chimeras of each other (both twins have full cells from their twin with their twin's DNA)
@@xxMpEGxx They can be chimeras by absorbing their lower half only. One woman took a DNA test for government assistance and her kids DNA matched with her twin and they were taken away for kidnapping even tho she physically gave birth to them.
That doesn't even make genetic sense.
When my mother was pregnant with me, they did an ultrasound and found she was having twins. When they did another ultrasound a few weeks later, they discovered that I had resorbed the other fetus.
Do I regret this? No.

My mother was a triplet. My mom and her sister were identical. In fact they shared both an amniotic sac and placenta. They had a brother as the third triplet. They were born at home delivered by their father and a neighbor. They were the first triplets recorded in Waco, Tx. All 3 survived to adulthood. Something unusual in 1930.
My fiancé had a fraternal twin, but he looked more like his older brother than his twin brother. When he found out that he had lymphoma, and needed a stem cell transplant, both brothers were tested for possible stem cell donors. The twin brother was ranked 4 out of 10 for an ideal match, but the older brother ranked 10 out of 10 and was a perfect match.
This is a bit extraordinary of a difference between the two comparing pairs of siblings, yet normally explained using classical genetics
yea, a fraternal twin is no different than any brother genetically, it's just gestation at the same time. So theres an equal *chance* for either bro to match him. all 3 brothers got a toss up of a random 50% of ec parents genes. It just so happened that the two that match got the exact same 50% from ec parents, but the 2nd twin didnt.
With a little bit of luck two twins may have different fathers.
@@larsjonasson2959 it’s possible, but more likely to happen in Soap Operas.
What a blessing! 🙏♥️
Someone once asked my twins "are you identical?" My son said, "no, we're infernal."

Oooh, what a give-away!
Was it a malaproprism (misused word) or was he making a joke? Either way its pretty funny lol.

That would be hilarious.
Hahahaha, I love that comment 😂😂

Omg 😂
I used to be a member of Twinless Twins International, a support organization for twins whose twin has died. A woman in our group was a mirror image twin. She said something that her dentist found amazing was the fact that even their cavities were mirror image. So weird
My youngest sibling was/is a Chimeric Twin. The twin passed due to my Mum's hypothyroidism very early on in the pregnancy. (My Mum didn't even know it existed until it had passed.)
My sibling absorbed his twin, but it turns out the twins umbilical code stayed in the womb. During my siblings birth the twins umbilical cord almost choked him to death. My freaked out Nanna removed the cord and did her best at attempting CPR.
My sibling is now 13 and healthy. When he was younger he would play with his imaginary friend. He said she looked like him and shared his birthday. He didn't know he was a twin at the time.
well, the spirit of unborn kids always sticks around!
and especially latches on to women who have had abortions! all the spirts are still attached to them today and some can latch on to their living siblings
It is a sad story, but I am happy that one of the twins is well.
@@AlicaSummer 😂🤣😂
okay, there, dude, who told you that?
What nonsense.
Premature infants are still jestating in spirit and must survive for the full term before they are present and acounted for person.
@@AlicaSummer No. Just no. That's not funny.
no one knew my mom was having twins until about a minute after I was born and the doctor was like, "Uh...hold up. There's another one up there."
Did the doctors not do the routine tests? Like sonography and such. This is interesting
This happened to my aunt and uncle. He was so small that he was hidden behind her though out the whole pregnancy and didn't show up on any of the ultrasounds.
Sometimes one baby is blocking another on the screen, so you would only be able to see one unless the other changed positions.
That's happened to the Bella Twins
This happened for most of my Mom's pregnancy. The doctor kept getting on her about her weight, saying she was gaining to much in till all of a sudden we both finally showed on a sonogram later into her pregnancy. I am a identical twin.
I'm actually a TRIPLET! My two elder brothers didn't make it though and now I'm their ambassador to the world
ambassador to the world lmao
The fact you said you’re “their ambassador to the world” proves your worthiness to the title
You have the power of one woman and two fetuses
Highlander of the womb!
That's 😢 sad
I am a triplet and I find it very strange that people don't find us as fascinating as twins. Even fraternal twins people view as somehow an identical duo with a special bond, but I have never come across anyone thinking that about myself or triplet siblings just because there's one extra of us? Lol. It's like people view us more as three's a crowd to a pair.
@Lauren
Are you an identical triplet or fraternal?
I think it's cool! I have twin daughters. I've known quite a few twins over my lifetime...but I've never met any triplets.
@@b.j.7837 Fraternal. Two girls, one boy, but my sister and I are not identical.
@@jater242 Oh wow! So, in other words, somehow, your mom's ovaries had released 3 eggs, and all 3 eggs got fertilized, and resulted in the 3 of y'all being born? That both amazing and really cool!!!
I guess it's because twins are more common and well-known in popular culture. Personally I think triplets, quadruplets etc. are amazing and very special. I can imagine doctors or scientists would also be very interested to study you. Has this happened ?
I have 30 year old twins who share more than 50% of their DNA. They are male/female fraternal twins. We have assumed for years that what happened is that they were one under-developed egg that was released and then split to two eggs prior to both being fertilized. I have no idea how whatever happened and I'm "okay" with not knowing - my kids are absolutely amazing no matter how their genetic oddities happened.
Uff da.....I wonder if "odd" is still politically correct description? 🤔
@@christinatweet6580 keep going and we wont be able to say any words.. words will become illegal.
my identical twin sisters have one section on one chromosome that seems different. Curious to know if that section codes for wideness in size, as they are one size apart in clothes. One's face is broader, heart-shaped and more like Mom's, the other's like Great-Uncle Art's oval, half Leningrad half Finn face.
Why is that odd? It's normal and easily explained by classic genetics...fraternal twins are like any 2 siblings. Any 2 full siblings can share more or less than 50% DNA depending if they get alot of the same DNA from ec parent or only a little of the same. 50% is just an average guess. Its just extraordinary for it to be like 90% or 10%
Ie
Dad dna is 20% ec of : A, B, C, D, and E.
Mom's DNA is 20% ec of : F, G, H, I, and J.
girl gets: A C, half of E from Dad and G, H and half of I from mom.
boy gets A, B and half C from Dad and G H and half of F from mom.
These siblings share 25% of the same dads DNA and 40% the same from moms.
They are 65% the same. It's totally random.
Or they could have gotten 50% of the same DNA from you. It happens even in siblings that aren't twins. They don't necessarily have to come from the same egg. Could be two eggs contain the same DNA.
When I tell people that i have a twin sister and they’re like.. “are you identical!?!”... I’m a man.. 🤦🏻♂️🤦🏻♂️🤦🏻♂️
You could be That last type of twin that shares 50 to 100% of the DNA I'm not going to try to spell that type of twin. Something with zygotes lol
So you could be identical ish
Chris Heichel For sure, we have identical features.. eyes, nose and mouth shape but that’s about it. I’m also about a foot taller than her though lol
@@darthsilversith667 That's cool you've got a twin, hopefully close
Chris Heichel Definitely!
Ok Paul
My twin and I are mirror twins. I'm left handed, my vision is strongest in my left eye, my natural hair whirls on the left. All of that is reversed on my twin. Also our dentist noticed that our dental x-rays are practically the same, just flip one x-ray over and they'll almost line up exactly.
do you organs on different sides ?
Wow... that’s cool. Especially the dental x-rays.
@@Q_QQ_Q Luckily it seems that all of our mirroring has been mostly external. Our organs are both normal. We do have some oddities like one being allergic to certain things and the other is immune.
@@reiakari Yo twin, did you just deleted my comment? That was just a joke
@@PrinceKashyap. I didn't see any comment from you. Someone from the channel got to it first, or it might be an error on CZcams's end.
I’m an identical mirror twin. It’s the weirdest thing. We are complete opposites from birthmarks all the way to teeth and personality. I’m majority left handed except for writing, my twin is right handed all the way. Sometimes it’s hard to believe we’re related and came out of the same birth canal. We’re so different sometimes I think doctors made a mistake. Lol. The weirdest part of it all is I ended up with 2 different colored eyes and darker skin than my twin. She has pure blue eyes, milky white skin and I ended up with one green and one blue eye with one eye having central heterochromia and beigey skin. Very odd.
Wow. It's interesting you say you have different personalities too. Do you feel a strong bond with each other ?
Maybe you had a triplet and are chimera.
Pics or it didn’t happen.😉
Sounds like perhaps there was a third embryo that perhaps you absorbed, hence your two different color eyes…
I always love to amaze people with twins in my family. My fraternal grandfather had identical twin brothers that both passed when they were 8 months old. My father is an identical twin and is the oldest of the pair. He fathered my younger brothers, again identical twins. The oldest of them fathered identical male twins 6 years ago. So we have 4 recorded uninterrupted generations of identical male twins in my family. We do have a great picture of my Dad and Uncle with my brothers each holding one of my nephews when they were maybe around a year old - 3 generations of identical male twins, Twins having twins having twins!
Wow
Are you from one of those places in Central America where "European doctors" immigrated after WW2? No offense, I'm just wondering
@@sarantis1995 No, Dad's side came here in the 1800's from Germany and settled in the Kentucky/Ohio area. Mom's side is German came here in the 1900's settled in North Dakota and French also came in 1900's settled in Minnesota. My parents met when dad was stationed at the Minot AFB. I do, however no reside in the central US, in Kansas...
that is truly spectacular!!! Always wished i had a twin :)
WOW!!! thats just amazing! could you upload that pic somewhere and send us the link here!
I WOULD LOVE to see what that looks like!! Mind-bogging!!
there was a women who failed a maternity test for her own kids, and it turns out she had the uterus of a twin she absorbed in the womb, so the test was only positive when sampled with DNA from her uterus. her names Lydia Fairchild
I was gonna mention her. I was enthralled with that story.
It is fascinating (and terrifying)!
@@sdrawkcabmiay Her sister wasn't and isn't sentient inside her. It's just Lydia, and her uterus is no different than if one were to have a donated body part.
What I dont understand is as the biological aunt she should have atleast registered on the dna test
@@sdrawkcabmiay of course, that's how dna tests work and the whole point of the story. But she would have had enough DNA in common to come up as a relative which meant if there was an investigation they would know shes atleast related to the kids which should have raised some eyebrows and also made it redundant to have to test the grandmother unless thry thought she was the biological mother. The father was the father too, so that's extra suspicious too. He would have had to have slept with the same woman to keep producing these children and the woman would have had to be related to the mother. Did the police think they had a secret relative popping out babies chained in their basement?

I know this isn't one of the above cases, but since we're all sharing :-) Because of they way they developed, the doctors told us our twins were fraternal. For 5 years, I kept telling myself I was being stupid for thinking that they sure looked a hell of a lot alike, but then my husband finally ordered a DNA test. It came back on April Fool's Day, and lo and behold, they were identical. Crazy how all these situations are possible!
I am an identical mirror twin. I'm the left handed one. Perhaps purely coincidence but we got cavities on the opposite teeth, are a bit near sighted in the right eye, and a very recent thing we both ended up with a cold sore scar on the exact same part of our lip. Also, definitely a coincidence, we got the very similar large scrapes on the opposite side of our front car bumpers lol There a lot of coincidences that just pop up in our lives like that. We live in different states, very far from each other and we don't find out till we see each other.
That is so interesting, thanks for sharing.
That is very unique. I don't believe in coincidences, perhaps you are psychic twins too?

I have always been told that fraternal twins are hereditary, not sure if it is true though 🤷
“In one case, a man fathered a child that had his twin’s DNA!” Um...
I think it means the dad was a chimera and his gonads had a different genome than the rest of him.
@@danieloneal7137 *Could have been bigger*
Possible case of chimerism or cheating.......
Hhhhhmmmm which one?🤔
I remember the news story. The man had no brother, just some absorbed tissue from what would have been his twin brother. No need to suspect cheating... unless he has a secret evil twin. O_O
@@danieloneal7137 Now that you said that, I think it is likely they have tested it.
Poor woman (and his brother) probably had a lot going on in their lifes until a doctor had the idea to test for chimerism in his reproductive organs.
I have mirror twins. Their organs are not reversed, but their external features and hand preferences are. There was one chorion (outer layer of the amniotic sack) and two amnions(inner layer) so there was a barrier between them but they were in the same sack. The doctors told me this means they came from one egg.
My friends twins are half-identical. The doctor told her that one egg and two sperm were involved. The egg could have split before fertilization, or perhaps when it got fertilized the egg decided to split soon after. Obviously no one knows for sure.
All 4 of our girls are healthy, active mothers of their own children now.
I had a pair of best friends in high school who were fraternal twins, but they looked so much alike that most people thought they were identical. It wasn’t until they stood next to one another that you could tell how different they really were.
My sister and I were told we were fraternal at birth because we had separate sacs & placentas. We did a DNA test this past summer (we are 30 Y.O.) and found out we are actually identical. About 1/3 of identical twins are this type...we start from one egg, then split very early on enough to develop separate everything. So on presentation/birth, it basically seems as though they are fraternal. You can only confirm identical vs. fraternal by a DNA test in these types of twins! It's actually more common than people realize...lots of stories online about "fraternal" twins who are actually identical! It's how we found out about it and decided to test ourselves. Everyone always thought we were identical.
I always thought the Olson twins were identical but when they stand together it's obvious they are not.
They might be that “‘more than 50%” type.
Can’t have 2 kids acting on tv as one kid and not be identical or close to it for 8 years straight.
Their little sister looks a bit like them too, just taller.
Me at the beginning of this video: ah, yes, I understand this information, I am comprehending this with my brain.
Me at the end of this video: so... there’s fraternal... and identical... and conjoined... and... bell peppers...
Bell pepper twins are my favourite type XD - i mean imagine giving birth and the midwife pulling out a conjoined bell pepper 😄

My husband (63) apparently has his twin in the bone marrow in his spinal column. It causes a lot of problems. He has difficulty walking, with no balance and very little feeling in his feet. Very little movement of his feet - especially the left foot.
He says he always knew he is to nice and intelligent for one. I then counter with "and too stubborn". 🤣🤣
I thank everyone for sharing their stories in the comments to this video on twins. I feel like even a few of your stories would make an incredible doco in itself.
What about the rare cases of women with two uteri who get pregnant almost simultaneously in each uterus? Technically fraternal, but definitely a unique case.
Uterus didelphys aka Double Uterus usually results in repeat miscarriages though.
Lisa Ryan True, but there have been a few cases like this one: www.health.com/condition/pregnancy/woman-with-two-uteruses?amp=true
As dissapointing as it is, they wouldn't be medically ruled as twins. They would be ruled "Multiple Singleton pregnancies". (I'm didelphys. My doctor was not laughing at my jokes during my prenatal appointment...)
T Massengill Awww how disappointing! Lmao
This happened to my mom when she was pregnant with me!
"less than 200 reported cases have been reported" Makes me wonder: how many unreported cases have been reported then?
Lol I think he said "how many recorded cases have been reported" though
I caught that too lol
How many reported cases have been unreported?
😂
That wouldn't make sense since how can you report how many cases haven't been reported
I remember seeing a program about surgery for two girls in Thailand who were conjoined, but strangely enough they weren''t twins but part of a triplet. One girl, identical to her sisters, was completely seperate, while the second and third girl were conjoined.
When in university, a huge, male student told us he had twice the amount of some organs in his body. He seemed similar to Shaq to my estimation. Holding a kitten once in one hand, you could not see it. I remember him having 4 kidneys, a heart that was one and a half sizes larger, stomach, normal genitalia normal.
One of my grandsons was born with 3 kidneys and all of them functioned properly. His parents made the decision for him donate the "spare" to an infant who was in kidney failure. Both children are doing amazing today. He was also born with a cleft lip and palate so we assume that the third kidney came about at the same time but developed properly. We could be wrong though since my grandmother also had 3 kidneys.

If you’re fascinated by the guy having his twins kid, there was also a woman who had her twin sisters kids! Her reproductive organs were unknowingly from an absorbed twin, so when she had a paternity test done, the kids came back as his but not hers! Eventually it was discovered when she gave birth to her current pregnancy with legal witness present and immediate tests showed it wasn’t hers either, until they checked cervical DNA samples, which matched all the kids. en.m.wikipedia.org/wiki/Lydia_Fairchild
That's incredible!!!
Wow! Thanks for sharing
I was thinking of that when he mentioned the guy!
I love how her last name's Fairchild.
Woah thats crazy! Thanks for the link!
I'm a mirror image twin. I am left handed while my twin is right handed, and when we walk, sits, stands or something I happens to always be on her left side which means she's always on my right side, and it's wired because we do it without thinking about it! I'm proud to be identical twin!
My grandmother was the 15th generation of twins. This included fraternal and identical sets. IIRC, most or all of them were left/right handed pairs. The left handed one always passed on the twin line. My grandmother was the left handed one, but her only living left-handed child was my uncle. Difficult for a male to pass on any twin genetics. My mom theorized that he could have been a chimera or have a vanishing twin.
@@b.schurman That's so cool i'm the left handed one, so I hope I will pass it on, I really wants identical twins!
For a second I thought I was a mirror image twin bc he’s left handed and I’m right handed but, we don’t look alike and we are different genders lol
I'm the lefty too! My dad tried to have my teachers switch me to write right handed in kindergarten because that was what happened to him but my mom wouldn't let him. She told him that I will always look exactly like someone else, and she thought that taking away my left handedness would take away from my personal identity.
@@armodillo7447 Boy/girl twins are always fraternal IIRC. My mom theorized that right/left handedness could have to do with which ovary side the embryo originated though!
My granddaughters are identical mirror twins. One is left-handed the other right. Hair whorls are on the opposite side. food tastes are completely different, personalities one is loud and extroverted the other is shy and quiet unless they are fighting. One tends to cross her legs to the right, the other to the left. One has been reading since she was four and the other is a talented artist. Their teeth erupted in the opposite direction.
i remember a heartbreaking story on the news when i was little around 30 years ago. A family had twin girls conjoined at the heart delivered via c-section. While at the time of birth both were alive and healthy the worst news came from the tests done.. with the best medical science had to offer they could only save one of the babies. There just wasnt enough of the heart to make 2 working ones and neither would survive if they stayed together sharing a heart.
The parents of course were the ones who had to make the awful choice of which to try and save... it was not disclosed how or why they made the choice they did but it cant have been easy. The surgeons in a many hour operation were able to save one child and fix the heart to work right for her.
they had a small funeral for the other.
i cant imagine the pain this family went through or the survivors guilt that poor girl might have for being the one who is alive..

To clarify their incomplete story of a man who fathered a child with his twin's DNA,he didn't have a twin.That is,a living one(Making this also a case of a vanished twin).
Daniell Bondad a more clear way to describe it is that this person has two sets of genomes. I mean, what does the separation between your DNA and your twin’s even mean? It’s all you!
Also heard a story about this happening with a woman. Her children did not share her dna because her womb belonged to her vanished twin.
That was the story I heard too. I figured it was just a different guy. As far as knowing which set of DNA is which probably has to do with dominance, whichever set of DNA there is more of? Some of them can tell, like I saw a video of a woman who had 2 different skin tones on different parts of her body, not like the melanin condition, it was just a slight difference. But other people probably can't tell, like one mom had a set of fraternal twin, a singleton, and another set of fraternal twins. So her doctor suggested that it might be possible that she might always drop 2 eggs and the 3rd child was just a chimera. In that case he's probably mostly one set of DNA and the 2nd set is not noticeable.
Dunmer Warrior I saw that one on tv years ago
@jowalter05 That was the one
I had twin boys with huge weight differences at birth. 9 lbs 6 oz and 6lbs 13 oz. Both blonde with greyneyes but as adults their appearances differentiated. The hospital lost the placental so we never did understand how they developed. But raising twins is a challenge no matter what their type.
My twins are mirror image twins. They were facing each other in the womb. One is right handed, the other is left handed. But they have completely different personalities.
My dad was diagnosed with "absorbing" his twin. I guess he had a surgery and the surgeon discovered he had multiple organs, some that were whole and functioning and some that were not fully developed and in odd spots. It was weird. My grandma cried because I guess she was prego with twins before she had my father but lost them in a car crash. It's a whole weird thing in our family.

My paternal grandmother had an identical twin. At family gatherings when I was little and the two of them were in the same room together I got them confused! As older women they would often dress the same for family photos and gatherings! It never occurred to me until I got into genetic genealogy that my father had two sisters - one full and one half sister! All because his mom had an identical sister! I met my dad’s sister/cousin many years ago. It was very spooky - that woman looked just like my grandmother!
That's lovely having I love twins, how are you Lydia?
I have triplet cousins that include one female & 2 IDENTICAL MIRROR IMAGE TWIN males...It's always fascinated me to no end...The boys, being utterly IDENTICAL, had 2 different colors of yarn tied around an ankle until they were old enough to take them off...HaHaHah. 🙂
My paternal grandfather was a fraternal twin. My dad's side also had identical twin girls, one of which had identical twin boys, and one of those boys also had identical twin children. My mother's side also has twins every third generation (my generation). With my luck, I'd get quadruplets or something...
I wonder if this is a common thing? I have cousins who are twins, and their dad and uncle were twins too.
I was next in line to have twins but when I found out that it was too dangerous for me to get pregnant because my pelvis is tilted then I decided that it’ll be better for me to get my tubes cut and that’s what I did
Not worth the risk
Good luck!

My nephew was born with 12 fingers.
I have seen quite a few documentaries about it extra limbs, adult conjoined twins , and teen girls two heads one body both normal able talk drive play sports, I have also seen a case where the one is dominant fully in control the other is mentally impaired . I think being conscious of your situation and stuck to someone would be worse then an extra limb
I know it probably was wrong of me when I was younger but I am an identical twin, but whenever I would have like a bad pimple for example I would always joke it was my other twin. I dont know where I thought to say that, I guess to make a joke out of being twins because everyone always bugged me and my sister about it. We would get stupid questions like if I hit your sister can you feel it. I guess I thought if I joked about it people wouldn't bother us as much about it. But I think the best question I ever got is how do I know which one I was. You would be surprised at how many times other kids would ask that and be serious about it, lol!
You know what would be cool? If that happened on the top of your head so you had, like, hair that was naturally two colors: brown and black, for example, or red and blonde, etc.
I've known a set of triplets since they were toddlers--they're now in their 40s--two girls and a boy. The girls/women are identical and the boy/man looks so much like his sisters that he could be semi-identical. I don't know if they've ever had DNA testing and I hesitate to ask something so personal. It does make me wonder, though.
Yes, in light of all the new info. becoming available, it would make one wonder whether one if these unusual situations occurred with those triplets.
I once worked with a guy whose wife "double ovulated" every cycle. When she was pregnant the second time and they were told that the odds were that she would have twins everytime she was pregnant, I think she had her tubes tied during the second delivery. It seemed very scary to me because I knew that I was not a suitable caregiver of most any kind. Fortunately, they were both excellent parents and I am now a very old-maid with cats. 😁
"Old", but 🤩 fabulous in yr own way, I'm sure!!
Nothing wrong with cats.
And then there's even fraternal twins that are born at the same time but when tested it results that they've been developing a different amount of months! I've met a woman that had this happen to her, there's a condition where the body doesn't recognize the pregnancy from the 1st weeks leading even to 10-12 weeks, so she got pregnant and then after 4 weeks got her period and thought she'd had a miscarriage, and then got pregnant again and when she got her first ultrasound there were twins. It all looked normal for months and then suddenly she went into labor on her 7th month of pregnancy and delivered her twin boys but one was 9months "old" and the other only 7 and had to be put into care for a couple of weeks. My mind was blown!
I have read about that It is a very rare genetic disorder and most of the time fatal for at least 50% of the patients that's including the child developing and the carrier AKA the pregnant woman
@@christianheichel Of course! I can't even start to imagine every possible way that could've gone wrong, or even the statistics behind each and every step that took place in such an unusual pregnancy.
I met a women who had the opposite happen. She had twins and one fetus had a medical problem and was delivered early; the other was left in to cook for another month or so. They were conceived at the same time, but had different birth days and legal ages.
This could be because she might have had a double uterus. I forgot what the term is.

I had a twin for a while. But my mother started hemorrhaging and lost one baby. They managed to stop the bleeding. And she was able to carry me to term. She had also miscarried twins at least twice before. She had 6 miscarriages in all.
I found it interesting that the Moffat's, a successful musical band from the 90's were a family with 4 boys. The oldest was born in March, and triplets were born less than a year later so all 4 boys are the same age for a month. The triplets were born as identical twins in one sac and the other triplet was a fraternal in the other sac. They all sang together for many years and eventually split up the band. The two identical twins continue to travel and make music together and have retitled their band as "Music, Travel, Love". The fraternal triplet continues to make music mostly on his own. I thought that was interesting and worth a share.

Imagine having legs sticking out of your chest for your entire life and then you find out those legs aren't technically a part of your body. Like, just when you thought it couldn't get any stranger, it does.
Want to see an image of this? One of the kids who had this condition was Deepak Kumar from India. Just search for his name and twin or parasitic twin and you will see. He was hailed as a reincarnation of the god Vishnu.
Oh gosh then come the arguments of whether or not the person can have the legs removed since it isn’t part of their body and it can’t consent
My family has 4 sets of twins all between the ages of 13-15, each set to a different sibling and their partner. We have no history of twins in the family prior to this boom. None of us used IVF either.

Good voice, too! 👍
The man fathering a child with his twin's DNA reminds me of this court case I heard of. Basically woman was trying to get child support for her child. They did a DNA test, paternity test came back positive but the maternity test came back negative. Questions of whether or not the woman was running some sort of scam did crop up. They did tests on the woman's parents, confirmed they were the child's grandparents. The woman was pregnant at the start of the court proceedings so they had a court witness in the delivery room who took a blood sample, DNA suggested the woman was the new baby's aunt.
If I recall, it was the opposing side's lawyers that suggested the woman's lawyers look in chimerism. Some further testin, the woman's reproductive organs were genetically her twin's. So genetically she was their aunt while being their mom.
Yep. Lydia Fairfairchild in Washington state. And it was indeed the prosecution who first raised the possibility that she was a chimera, after seeing a report of a similar case elsewhere.
I've heard that story. My high school health teacher showed a video talking about it back in freshman year.
This is confusing
That’s gotta suck though never being able to have kids of your “own”
I remember hearing about that! So strange and confusing and fascinating. Even if she is technically having her sister's kids, they're hers, no matter what! Maybe her reproductive organs weren't strong enough so the other twin helped her... Yes, metaphysical, esoteric curiosities. I am filled with them!

My mother (born in 1953 at home )was a mirror twin and her organs are reversed. My mother did not find any of this out until she was around 20 years old. She was at the hospital sitting with my aunt (her SIL) when she got sick. A nurse came and took her down to the ER because her fever was so high. Her appendix was about to rupture, so the doctor had to do surgery to remove it. After she came out, her doctor asked her if she was a mirror twin. She said no! When my grandparents got down there the doctor asked them, if my mama was a twin, and they said yes. My mama had no idea. Her twin was stillborn. They asked how the doctor figured it out, and he said my mama's organs are on the wrong side of her body, he had to cut all the way across her stomach to find her appendix. This was the first time that Mama ever heard this. My grandmother said, that Mama's sister was in her own sac, but that the doctor had to separate the two. Mama's twin was not formed from the waist down (it was described to me like Mama's twin was growing out of my mother's lower back). The doctor told her to always tell her doctor that she is a mirror twin. Now fast forward another ten to fifteen years and it was discovered that my mother got all of her sister's organs below her stomach. Her X-rays, CTS,
and MRIs have scared the crap out of doctors before!
Fascinating ✨
There's also quaternary twins, where two identical twin sisters have babies with two identical twin brothers at around the same, causing both babies to have extremely similar DNA, similar to twins

In 2008, my twins were born mono- amniotic, mono- chronionic (same amniotic sac, same placenta). We were told it occurred in less than ¹/² of 1% of identical twin pregnancies. One twin (she passed at 8 months after an attempt at open heart surgery) was born with a 2 vessel cord and multiple heart defects (at least 6 total), and they had some of the the mirror image qualities, including her heart (dextracardia). We were told had the original cell split just a day or a few hours later, they would have been conjoined.
I had mirror image twins in 1990. One twin had heart defects. Transposition dextracardia VSD ASD pulmonary stenosis malformation. Basically a mess. Surgery was carried out 1991. No full correction was possible but repairs were done. However it resulted in a massive insult to her brain. She was nit expected to live beyond her second birthday. She has just recently passed at 31. She was amazing and fought to survive over coming many further problems. She lost her sight was unable to move severe learning difficulties epilepsy eventually undergoing surgery on her hips and her digestive system. I have not heard before now of any other twins who were mirror image and one having cardiac defects. The Drs said the cardiac problems were all down to the mirror image.
Very high risk pregnancy. My grandsons were mono-di twins. Still high risk

How is the twin that survived doing?

We had a set of twin boys in our class. They looked absolutely identical. So much so that even the mother admitted to having problems to tell them apart. The only difference in them was that one had a mole on the right cheek and the other one had the same mole on the left cheek. They really were like reflections of one another.
i Used to coach twins like that. Both Girls were 6 feet tall, one had a cheek mole, the other didn't. One was a much better volleyball player.
If they had moles on opposite sides of the face how did the mom have a hard time telling them apart? I have always been able to tell twins apart. There is always a tell I even when identical. Personalities will be different.
We had that in junior high, But in High School, One twin joined the(American) Football team, the other joined basketball. After four years of commitment, and the Puberty, they DID look like two different people

I remember a pair of twins in high school who were both redheads freckled. They looked so similar that if they dressed the same you would think they were identical. Even though, they were brother and sister.
The fusion thing is definitely possible. My sister initially had a twin in utero, at my mum’s first scan. Then, by the second scan, it was gone, it had been absorbed by my sister’s foetus!
My biology teacher told me there’s a theory that all left handed people are mirror twins who’s right handed counterpart past away. It seemed not very plausible but as a lefty myself I found it interesting
Oof I’m a lefty and my sister is a righty. We’re four years apart (so definitely not twins) but we do get asked if we’re twins a lot. Lol Rip nonexistent/non born twin. I don’t think this is true though because we lefties are our own people like we used to be as common as righties, but then people thought we were devils and started killing us off and we started becoming pretty rare. Yay!
Epiccatqueen 3312 oh dang that’s true, is being a leftie genetic? My parents and grandparents are all righties?
Autumn Franklin no it’s not really. I read this whole thing on it but it’s like if both parents are righties then their first child will most likely be a righty and their second child will most likely be a lefty. There were a lot more statistics and stuff but the only one I memorized was that one because that’s what applied to my family
@@Epiccatqueen-un1ew I know lefties haven't been treated kindly in history (to put it lightly) but I thought it was still a recessive trait?
Autumn Franklin this doesn’t entirely work for ambidextrous people like myself. My brother was left handed and when I was little I copied everything he did until one day I burned my left hand and then I was a righty... now I can use both hands. Although I usually print with my left and do cursive with my right. I do sports left handed and I eat left handed and I brush my teeth left handed but I draw right handed and I brush my hair right handed. Not sure if this is anomalous or normal? Actually all my siblings are left handed except me. My brother and my two step siblings. Oddly, not a single of our 4 parents combined are left handed.
So I am a monozygotic twin. However my twin and I do not look “identical” at all. I am 5’8” 140 lbs my sister is 6’0” 200+ (mostly muscle and bone structure). We had different hormonal levels through pubescent developing years. People through my entire life have continually told us we can’t be twins or “oh so y’all are fraternal?” (Everyone thinks they are the expert..). We were born through a cesarian or C-Section, my father said he was present when the room when the doctor preformed the operation. He told us of how the doctor called him over saying “you don’t typically see this”. He showed that we were in the same placenta (identical twins). We even have different eye color, our eyes look so similar, yet hers are a cool tone green and mine a grey blue. I believe we are what you called semi-identical twins, one egg, fertilized by 2 sperm. Even medical professionals have tried to say its impossible we are identical, but my parents know that we come from one egg. Ultrasounds and the birthing process have proven this to them. In my 23 almost 24 years of life I have never found an answer until now! Even before this video I suspected perhaps one egg and 2 sperm. I am a biology major and this has always fascinated me. Thanks for the info :)) I have always loved this channel.
I went to school with a girl who claimed she and her brother were identical twins. I always thought she meant fraternal but now watching this... maybe she did mean identical. Or that last one...

I developed 1 week later but we had 2 amniotic bags and one umbilical cord but we are monozygotic twins!!!I hope i will find answers like u!!

Interesting! I’m a male with a twin sister, and she had a teratoma cyst on one of her ovaries a few years ago, that needed emergency surgery. She needed a blood transfusion and I immediately realised why it was important for me to donate blood over the years (we’re the same blood type). After watching this, the teratoma could have been any manner of things!
I had mono/mono twins last year in July.. they’re now nearly 18m . I wonder what and if they’ll have some kind of mirroring. They both also have a mark on the side of the face above their eyebrow that Mirrors each other & I wonder why. Like maybe it happened when they spilt in my body. Miracle babies . They survived cord entanglement and all
I am a twin and mirror image of my sister. I have a non pigment mark on my upper thigh, and my sister has a darker mark on her opposite upper thigh, as if she took my pigment from me.
I was a twin in the womb. I didn’t absorb my twin. He was miscarriaged so... I’m a twin that’s a only child

My brothers twin was also a miscarriage, but idk if that has to do with his current condition either cuz my brother came out Albino as well with some mental learning disabilities. Idk if those are related at all but it always poked my mind whether it's connected or not
Same I was a faternal twin. But my twin was miscarried.
Jinhua Official me as well!
When I joined the Navy, there was lots of confusion about my DNA.
As it turns out, I'm a tetragametic genetic chimera with a near even split of male and female genetics.
(Not a hermaphrodite or pseudo-hermaphrodite tho)
Jeska what does that mean though? How do the male genetics affect you?
@@nika5318 Roughly half my DNA is male, and half is female. As it was explained to me, the egg either split, or there was two of them together (like a double yolk in a chicken's egg). Each then got fertilized by sperm, and then sometime in the zygote or blastocyst stage, they merged into one.
Now I have Blaschko's lines from the patchy mashup of my skin (and the rest of my organs) with some areas being predominantly male, and others being predominantly female.
I deal with both male and female cycles of hormones (yeah, it sucks twice as much, but like everyone, I have learned to live with it - mostly). And whenever there are articles or topics about how guys are or how girls are, I tend to relate to all of it fairly equally.
In terms of how I feel, I'm bi-gender simultaneous (I feel, think, and identify as both male and female at the same time, 100% of the time). But since more of my male characteristics are recognized IRL, I tend to express as a male IRL, and as a female online.
Feel free to inquire more if there's anything else you'd like to know, I'm quite open about it. There's also an expert's forum thread where I go into a lot of detail and people have asked me many questions too. It can be found here:
forums. nanowrimo. org/t/ ask-me-about-being-a-genetic-chimera/ 117826
(Minus the spaces)
Jeska so because of the skin mashup do you have more darker and visible hair on the male skin and less on the female skin? Are the hormones only affecting the bodyparts and cells to their gender or is the whole body Influenced with both hormones the whole time. Thank you for elaborating.
@@nika5318 Due to the migraines I suffer and my sensitivity to sunlight which aggravates them, I tend not to go out into the sunlight very often. However, when I do, the male patches of my skin tend to tan quicker and change their texture to be a bit tougher (for lack of a better way to put it) while the female areas tend to burn a bit more and stay softer. This is the only time when the differences of the skin are easy to notice. Other than that, the majority of my chest has female skin and is smooth, soft and hairless, while the majority of the skin on my legs is tougher, and has more hair.
My face on the other hand is... odd. I have facial hair like a man (mostly), while there's a distinct line on my scalp near the hairline which almost always seems like it's at war for which set of DNA dominates. My hair then looks, feels, and acts like female hair does, as opposed to male hair (as many barbers, hairdressers, and a couple makeup artists have commented on when working with my hair).
One interesting bit to know is that I have both types of ear wax in my right ear, with the dry flaky kind for the majority of it and the sticky goopy kind only near the ear drum, while the left side has mainly the goopy kind.
As for the hormones, they effect my entire body. I don't have a uterus, so I don't get periods, but I still get the cramps which would come with them as if I did. As for the emotional swings, I get all of that.
Also, many guys think that guys don't have hormone cycles the same way girls do (which simply express differently due to it being a different dominant set of hormones), and that idea is predominant only if they are woefully unaware of themselves. People could learn a lot just by paying attention to when they feel more or less "angry at everything" or "chill". Sadly, there's so little education for guys that helps them understand or learn how to deal with their hormone cycles. I think a lot of good could be done if more self-awareness and skills to help deal with and handle these cycles and the feels that come with them were taught to people (guys and girls, tho girls get some of this, which I think helps overall).
[Edited to correct some syntax]
As a side note, I see in some of the other comments that there are stories about mix-ups and problems about children with chimera parents. I've had some of these problems myself. (Warning tho, that part of my life is a very real and personal tragedy - So while I'm okay sharing some of it and answering questions, it may not be something everyone will feel okay reading about.)
That said, if there are questions about that, feel free to ask.
In 9th grade, I talked to my mom about genetics we were studying in school. She told me my twin & I were identical. I corrected her, pointing out all the major differences between us. She said the doctor said "one sac, identical". Did some research, (pre-computer days) & learned identical twins that look nothing alike is possible but rare. (He's a "leftie", I'm a "rightie", he had straight hair he lost in his 20s, I had curlier hair which I still have in my 60s. He was inches shorter with a totally different personality.). Since you did not cover this, can "identical" twins be so polar opposites? (He moved, so DNA test is out) Also, if one twin does something & leaves trace DNA, can an identical twin be also implicated as they share the same DNA after a split?
That has actually been a defense and there has been a case where someone got off because they could not tell which twin committed the crime of two identical twins when they were both in implicated but things like fingerprints are unique so DNA is the only thing you could leave behind That wouldn't be able to differentiate identical twins if there's any pictures of the side of your head your ears are unique finger prints foot prints if he's a different price as you pointed out I would not suggest trying to commit a crime because you have a identical twin because that's just one thing but if that's all they have then technically you could get off with lack of Evidence reasonable doubt
@@shellnet411 actually, I'm curious because he's the one likely to commit a crime. Have read a few cases where that defense was used. Even heard about one with triplets.

Vanishing twin syndrome wasn’t really well known back then so they always assumed it was an error with the first ultrasound machine. Until a couple years ago my brother gifted us all DNA kits for Christmas and mine came back really weird. It claimed I should have a different eye, hair, and skin color as well as freckles and curly hair. I thought they’d accidentally mixed up my sample with someone else’s but it also came back as a DNA match to my mother and brother. Later I took another test using a different DNA source and it came back not only as my correct phenotypes but as a SIBLING DNA match to my first test.
And I don’t know if it’s this way for all chimera twins, but I have really bad autoimmune problems. The docs can’t say for sure if it’s related but considering my condition is full-body rather than localized I’d say it’s fairly likely.
Hey, I hope you don’t mind me asking but what’s the 2 DNA sources you use was it like saliva for the first one and then like hair for the second one ? Also did you use 23 and me ? I always thought those DNA tests kits let you send saliva only. Sorry for all the questions, I’m just really curious lol
@@micaella2294 it’s np. They do typically always use saliva for recreational DNA tests like ancestry or 23&me, but I’ve had medical tests done for my autoimmune issues that used blood instead, which yields different results from my spit.
Funny enough some of the few things my first test (saliva) did get right was that I can taste calcium, am sensitive to sweet but not bitter, and don’t taste soap when I eat cilantro. AKA, the sample taken from my mouth was really only right about the parts of my DNA that affected my mouth.
My friends daughter is a chimera too - she has two different coloured eyes, one is golden brown, the other is really dark brown - and she has two different skin colours that swirl together in different areas.
@@tuathadesidhe1530 That sounds so awesome! I hope she learns to cherish and appreciate it later on in her life. Early on kids will be cruel though I'm sure. :(
I once knew a girl that didn't have different "skin colors", but patches of pink skin like flower petals all over her body. It looked really, really cool and in a good way was as unique as her personality.
Chimera twins is one of the most interesting things I've ever seen! I think it's freakishly cool, I hope you don't have too much pain going through life! You're awesome :D
I had a twin that was stillborn but I didn’t find out about her until I was 32 YEARS OLD, when my mom accidentally revealed the secret I had never known. I was born 5 weeks premature in an emergency c-section because, well, everything went to hell. All three of us nearly died. But ultimately, my twin didn’t make it while I did, and thankfully so did my mom. I was only a little over 2 lbs and was in NICU for a bit, of course. And thing is, growing up, I KNEW all that, about my birth being an emergency, premature, complicated, scary, etc, but my family just never ever mentioned the whole OTHER BABY. They’d been preparing for twins, named her and everything. It’s so sad.
I did get a younger brother two years younger than me. Because of my tiny size, people thought he and I were twins. My mom even dressed us alike. I realize there must’ve been some psychological and emotional pain going on. My poor family.
But this news has also been a real mind f-*# for me! I keep thinking about who she might’ve been, what she might’ve been like, how different life might’ve been. And my poor parents were so devastated they never even planned to tell me about my own twin. To top it off, I have several debilitating autoimmune disorders and am physically handicapped. So I wonder, would we have both had health issues, or would she have “the healthy one”? How tough that would’ve been. Worse than the competition to be the “pretty one” or the “smart one”. I grew up knowing several sets of twins (and one set of triplets.) Now I observe twins much more closely, and wonder.
I really have just been so stunned by that revelation. I don’t ask my parents more about it because it’s clearly still a deep wound for them. I grieve a little, too. A twin I never knew about, a butterfly.
I'm sorry for the loss you and your family are still dealing with. I can't imagine.
Hannah comforting
@@justincoleman3805 lol!!
Are you glad you found out about your twin or would you prefer not knowing anything about this?
The fact that she was stillborn makes me think YOU'RE the stronger one, so she might have been worst of, live life for you AND for her! You may not have known her but she's with you always! In a way she sacrificed herself for you
My Great Grandmother and Great Aunt were so identical the only way to tell them apart was the frames of their glasses lol
The matter of Mirror-Image twins perked up my attention.
My step-mother apparently had mirror-image internal organs. She told me this out of the blue one day. (I have to take her word on it.)
Anyway it raises the question: Was she born a twin and she never mentioned her? Or was she conceived a twin, but lost her sister early on? (i.e. her mirror-image twin, i.e. a conventional L/R organ-layout girl?)
Has this ever been considered as the development-pathway for Situs inversus? Maybe the ONLY pathway?
And just to pull things in a weird direction: I have 'Colonic Duplication' - I am the Man With Two Bowels (not Brains!). I've often wondered how such a quirk sets itself up during foetal development. Is my spare poo-tube all that's left of my original twin brother? And more importantly - can I now call him "My Evil Twin Brother" and blame him for every bad thing I do?
My twin grandchildren have an unusual story. One baby (a boy) was an IVF baby and the other baby (a girl) was naturally conceived. So fraternal twins in a way but at different stages of development... a rare occurrence. The babies had separate placentas and sacs. The girl was much smaller than her brother all through the pregnancy and they were delivered by C-section at 35 weeks. He weighed 2 kg at birth and she was 1 kg. They were in NICU for many weeks but did not require breathing support, just feeding tubes. The twins have recently celebrated their first birthday and their size difference is still very obvious. He now weighs 11 kg and she is 6 kg. Being bigger and stronger, the boy reaches developmental milestones about two months before his sister. People often ask what the difference is in their ages , our reply is 4 minutes!! They are our miracle twins.
Wow, that is amazing. I know a guy who was also born very premature, and is just quite short and has dyslexia. Not sure how the dyslexia relates, it probably doesn’t, but as he said: “I’m short, can’t even read, and I still get girls, so there’s hope for everyone”. Made me laugh.
How many months apart were they development wise?
@@thiccredgyal3404 Physical milestones like holding their head steady, rolling over, sitting up etc were about 2 to 3 months apart. They got teeth about the same time, started to speak at the same time.
wow❤
@@sandraleech2060 my friend's twin sons were similar
Worse, never prepared to hear "twins" at 3 months pregnant, later during medical checkup exam and Ultrasound at 20 weeks, I asked as a joke "are there three?'" - let me see said technician "yes, here is the third fetus"..... shock!
Blessed with healthy triplet boys born at 32 weeks.
Were they okay? Being born so early, I mean?
@@criminyworldriseedify8962 yes they were born at 32 weeks and 3 ilbs each after 3 weeks in NICU they came home at 4 lbs each - first year was a nightmare but every year afterwards got a bit easier. They are 25 now. tkx
were they identical?
Can we hear names?🥰😅
@@anjali4440 over 95% of naturally conceived triplets are a "pair and a spare" identical twins and their fraternal triplet. So yes two are identical and the third is not.
I knew a pair of fraternal twins who were conceived a month apart, but were born the same day. There was a marked difference in their stages of development all throughout the pregnancy and at birth. By the time I met them, they were fairly evenly matched in development apart from the typical differences seen in children of opposite genders. The girl was a little smaller than her brother.
My great grandmother had 3 sets twins, two sets triplets. 11 single total 21. She outlived 20 of her children. My mom lost her set of twins. My mom's sister 1 set twins. My brother 1 set twins. My dad's brother and wife 1 set twins. ALL BOYS. My sister 1 set triplets. 1 boy and she lost the only 2 girls. We All go for scans the moment we know we're pregnant lol.
6 +6+11=23 not 21....
@@joandougan8682 thanks for correcting it. It was a typo error.
Whoah!
My brother and I were born conjoined twins. To separate us they had to remove the entire left side of my body.
I'm all right now.
I thought this was serious 😂
@@katyungodly lol me too xd
Wtf 🤬
@@tangiechapman6219 why are you so mad?
What's left of your twin?
This video makes me happy to have made it out of the womb... without any extra bits or missing bits or whatever
LOOOL indeed
That you know of...
My pinky finger has a little chunk taken out . But whatever
When my Mother gave birth to me, it was at that point that she found out she had 2 wombs & 3 ovaries.
! That would be some surprise!
OKAY that brings up LOTS of questions, oh my goodness
@@ciderofthearctic392 She was a surviving twin, she inherited part of her sister's female organs, according to the doctors, it was most likely an identical twin. My brother is a surviving twin, he only has one set of male organs, lol, and I was pregnant not with twins but two babies at once. One in the womb and one in the ovaries, there was 2 weeks difference between their ages. I miscarried the one at 6 weeks, and when doctors checked me after, they were baffled that I was still pregnant, I ended up having a left-side tubal ligation. Twins run in our family as far back as 8 generations.
@@sandrawalters Oh jeez- are you okay?
@@ciderofthearctic392 This was 35 years ago, physically, I am okay as far as that goes. However, I still remember losing the babies and it still haunts me to this day.
Thank you for asking.
Fascinating to me reading through the comments and watching this clip how many diffferent variations of the human condition exist.
To anyone who has situs invertus and has had be been hospitalised for exams including an abdominal scan, just know you've made the whole medical team's day and we'll all be hoping for a rapid recovery.
If I had situs inversus, I'd get it tattoed somewhere.
@@sohopedeco One of the more sensible reasons to get a tattoo. If I had that, mine would say "Wrong side, bro!"
I have a buddy with it. Things they don't talk about that the hàirs in there nose and ears don't fully form. He gets sinnus infections alot. He also started lactating, had to have breast augmentation to remove the breast tissue. Real messed up stuff.
Agamemnon backwards, too
Eldon Erc There’s supposed to be hair in your ear?
"A man fathered a child that had his twin's DNA!" Yup, that's the mother's story and she is sticking to it
@@suzip240, Lydia Fairchild is a fascinating case of how chimerism can affect someone's children. Lydia Fairchild and her husband were expecting their third child when they separated. She applied for child support and in the DNA tests, it showed that she wasn't the mother of their children.
A court officer had to attend the birth of the third child and immediately take DNA from Lydia and the baby, again showing that the baby wasn't hers. She was in deep trouble, facing allegations of fraud and the threat of having her children taken away. They ran DNA tests of the children against Lydia's mother and found that Lydia's mother was their grandmother. Then did more DNA tests on Lydia; while her skin and blood DNA didn't match, her cervical DNA did match as their mother.
Haha, a joke about infidelity. So original... (if it's not a joke then you really think scientist are a bunch of morons)
@@cepahreinholt8710 dude. If you don't like the joke, you don't have to give it further attention. You don't have to be rude.
@@cepahreinholt8710 are you doing okay? How is your day? Also, sorry if my earlier comment came off as chastizing, I don't mean to to be mean.
@@fleurgymcheurgy9267 I'm sorry too. There was just too many comments about that in my opinion and I wasn't sure all of them were jokes.
There are also cases of faternal conjoined twins too, which I find really fascinating. Because obviously, they would have to fuse, rather than fail to fully split from a single embryo.
There’s one set of twins you missed: fraternal twins with different fathers. It has even happened where one child was white & the fraternal twin is biracial, with a black father. The woman ovulated with 2 viable eggs, one being fertilized by one man, & the other egg being fertilized by a different man within a short duration of time, both fertilized eggs implanting.
This
Heraclese was one
yes black father white mother faternal twin babys one had dominant red hair fair skin , the other miloto
Someone was cheating...
Ian Gates I corrected your spelling on the “M” word, & CZcams censored it twice. Biracial is the preferred term, regardless
Me a triplet standing next to my 2 other sisters....
Every adult ever while growing up: Are you guys twins?
The three of us speaking at the same time: YES
I would pay to see this 😂
twins?
Lolol
So you’re telling me that you’re the only one of the triplets that don’t look identical to your siblings?
@@hamstersdailylife4938 non we all just look like siblings we're not identical..people will apparently not understand that 3 sister the same age ate "triplets" idk if that makes anymore sense or not 😂
Such an incredibly interesting video, and this guy has an awesome cadence to help make this topic interesting to those who are less interested.
My mum was told she was expecting an 11lb baby, but minutes after my brother was born, the midwife said that there was another one in there. It was 1971, so no scans.
My poor mother delivered me 2 hrs 20mins later. I was gestationally 4 weeks behind my brother according to the doctors and they said we had been conceived a month apart.
Sadly, my other half died in a car crash when we were 17, which absolutely devastated me, but today, i cat help but think im supposed to be here.
As a father of twins, I really liked that joke.
We had a type of fertility help that often leads to twins, but has a small but realistic chance of more than 2.
When my wife had her first sonogram, the doctor said: I see 1 baby, 2 babies...
And I immediately said: No more than that, right?
LMAO! I have friends that got in vitro fertilization, and as a result, despite hoping to be lucky enough to just have one baby, they got fraternal twins. It was the same with them, haha. As an aside, I have two kids, and they're not twins, except in the Irish sense... But when I was pregnant with my daughter, I got so big, so fast, that my ex-husband's first breathless words when they were first doing the sonogram, were... Lay it on me Doc, how many are there? Thankfully, there was only one, my daughter... but nevertheless, his response reminds me of yours, LOL.
Hahaha oh my god I feel that.
Totally different backstory but I remember the lady doing the ultrasound saying "yes I see a heartbeat ..... And there's another heartbeat"
We were like what?... And I can't remember what she said but it sunk in and she handed me a box of tissues and I yelled "Tissues aren't gonna help me now!!"
Good times...
One baby, two babies, THREE babies, Mwahahaha!
@@charlottegrace6656 That reminds me of Monica and Chandler's twins where the birth mom thought "both heartbeats are strong" meant the baby's and hers, not two babies.
