My husband and I have 3 kids, 2girls, 1 boy they all look alike. It's like I gave birth to the same child each time. We're both mixed but I guess our genes are strong together
Just looked up dominant genes cause it came up on a vladtv video.. I search up random stuff like this to learn lol already have an idea what these are just cant ever learn too much
what is the mechanism of dominance? how does one trait get expressed over another and what is in its make up that makes it dominant. expression is the result, but what is the cause? I can not seem to find this answer
Question, if a blonde couple have children, their children should be 100% blonde right? Since if there are any black hair alleles in either of the couple, it will show due dominant trait correct?
How does one make sure that which one would be dominant or which one not ? How can mutation be hereditary when Dominant alleles always do cover the recessive one's ?
Hello Madam, I have a small doubt about the gene expression .my doubt is ,in a heterozygous state , the gene which expresses is dominant or the gene which is dominant expresses? For example, y can't the gene responsible for the dark colour of the skin dominate that which is responsible for fair skin Or Is it always true that the gene which produces tall plants ( the tall gene )dominate the gene that produces the dwarf plants(dwarf gene) Or Is there any chance that in a dwarf plant tall gene being dominated by dwarf gene? Or Is it like, only in homozygous state dwarf gene expresses it self otherwise no? Or Is it the phenotype which tells us which one is the dominant gene or is there any chance to know which is gene is going to be a dominant gene before it's expression? Or what is that which determines the dominance of one gene over the other? Please clarify my doubt which is a genuine one Thank you
then you got no widows from your dad but in the future your chilrden could have a widows peek because your mom is carrying that ressive trait and if your parnter has a widows peak or hes carrying that as a family ressive trait your child could have one
how come me myself a boy by the way, and i have 2 sisters how come I'm the only one who has my mothers nose, head shape, double crown, sleep like my mum, and my 2 sisters have my fathers nose, and have the same trait of how he sleeps
my mom has brown eyes and my dad has blue eyes. for some reason one of my eyes is fully brown, and the other one has a little part of it that's green. no one in my family has green eyes so i'm confused why this happened
@Mason McCarty green, blue and grey eyes are recessive, it shows a deficiency, they don't even absorb the same high levels of light as brown eyes, also it's likely that blue, green and grey eyes indicate psychopathy in the person who has them.
i have freckles and blue eyes my mum is covered in freckles but doesn’t have blue eyes i thought both parents needed to have blue eyes my dad only has them
@Daniel Fritzsche thanks for the info, my mum actually has green eyes and my older sister has brown eyes, my younger sister has green and my other sister also has blue 😃
But so the dominance or recessiveness of a trait applies to a whole population? That is, is having green eyes a recessive trait? This means that if I have green eyes I must be homozygous for that trait?
Yeah my brother has brown not that dark but darker than average I would say though he had golden hair as a baby and toddler but also I have a cousin which had darker hair as a baby and lightened now but hes still a toddler
So say a man with black hair has a baby with a woman who has blond hair. Black is the dominate allele and blond is the recessive so the baby’s hair comes out black. Now say that baby with black hair has a kid with a women with blond hair in the future. What color hair would the baby be??
Great question! Since offspring #1 has one dominant and one recessive (Bb) and the blond has all recessive (bb) their offspring could have either color of hair:)
I understand all of this, but what determines if a gene is dominant or recessive? For example, why is the freckle gene DOMINANT and the no freckles gene is RECESSIVE? Why not the other way around? Or why brown eyes are dominant and green eyes are recessive?
I’m no expert, but my understanding is that at some point in time all gene variances came from a mutation. A mutation is essentially when by some random act of nature a gene becomes different from either of the parents’ genes. For example, perhaps at some time no humans with red hair existed, until 1 person’s genes randomly mutated (at the time they were conceived), causing the gene for hair color to vary slightly in a way that results in red hair. So I would hypothesize that whichever way the mutation happened to occur was essentially a random act of nature. However, it is more likely for us to know about dominant mutations because you only have to have one to visibly express it. If a new mutation is recessive, then you would need both parents to happen to have that same random mutation and also pass on that piece of DNA to the kid for it to become known. Theoretically, there could be thousands or even millions of “undiscovered” recessive genetic mutations that people are walking around with right now, but we don’t know how they would present because they are the only person who has it and they would need to have a kid with someone else who has it in order to have a chance of the kid presenting with it.
I saw this one stupid graph that doesn't seem true! It was saying that Type 0 blood is recessive then why do most people in the world have Type 0 blood?! It's called the Universal donor for a reason! Also, I have black hair that's straight (because I'm Asian) and I am left handed! If left handed is less dominant then why does my brother and I have left hand and the only right handed one in the family is my mom! My dad has left handedness too! So that makes 3 our 4 people in the family with left handedness!
The full panoply of eye colors and decorations are controlled by something like 12 different, independent genes in the genome. OK, let's see a punnet square which shows the whole situation.
the UNCLE? the uncle has nothing to do with the reproductive process. but, yes, a child can have the freckles if the recessive gene skips a generation through one of the parents.
oh well we meet up again Another class for another known teacher teach one thing that im thinking about is why dose the teacher in our class dosent want to teach us just give us the ... oh now i know why .... hope she gets better soon
Thank you so much. I was confused and struggling with this, but now I understand what it is. Again, thank you😊
My husband and I have 3 kids, 2girls, 1 boy they all look alike. It's like I gave birth to the same child each time. We're both mixed but I guess our genes are strong together
I wish you were my biology teacher. Great help!!
Punnet square
me to
This is my teacher
@Abdiel Velez this is my teacher too
thank you so much, I didnt get this at all for my bio class and you helped me so much
Really it is amazing thanks for your time for us
this was awesome! it really helped me understand! thank you so much!
Nice teaching (from India 🇳🇪)
Clearly nobody's heard of the Punnett square.
Derrick Marler I have
I have -not-
Just looked up dominant genes cause it came up on a vladtv video.. I search up random stuff like this to learn lol already have an idea what these are just cant ever learn too much
Great video 👍
You teach AMAZING!
what is the mechanism of dominance? how does one trait get expressed over another and what is in its make up that makes it dominant. expression is the result, but what is the cause? I can not seem to find this answer
So helpful, thanks😃
People with widow's peaks want you to think they're not vampires.
If you can respond, when you mean for recessive. It can only show if both are present. Could you please elaborate on that please
Just great love it
i love this. what is the difference between traits, characteristics and gene
Parenal generation(P1)
Question, if a blonde couple have children, their children should be 100% blonde right? Since if there are any black hair alleles in either of the couple, it will show due dominant trait correct?
Thanks it was really helpful :)
So basically dominate traits have a 2/3rds chance of showing and non dominate have only 1/3rd??
tankyou so much was struggling till I found this
Ahhh I love this stuff. 🧬 🧬 🧬
gr8 video
Wow man thank you for your understanding and help me with this
this really helped thank you so much
I FINALLY UNDERSTOOD THIS TOPIC LMAO TYYYYY SMMM!!!!!
Nice...
U are genius
What if both parents have brown eyes but the child has hazel or greenish eyes?
How does one make sure that which one would be dominant or which one not ? How can mutation be hereditary when Dominant alleles always do cover the recessive one's ?
@MudShark huh ? Didn't get you here.
Amazing
thank it would help a lot
Thank u .... so much ...
Wait, how would you define which parent is Dominant or Recessive ?
Not parent but alleils parents are just like you having mixed alleils
you are a great person, love u, u helped me so much (from french)
Ohh..nycc
But what determines something to be recessive or dominant?
the second she said kachow i subscribed
This is really helpful
Thanks that helped a lot
What is the definition of dominant in genetics?
good vedio
So how do people end up with big noses and recessive facial features?
Because if your parents both have more recessive genes your most likely going to have that recessive gene.
Hello Madam,
I have a small doubt about the gene expression .my doubt is ,in a heterozygous state , the gene which expresses is dominant or the gene which is dominant expresses?
For example, y can't the gene responsible for the dark colour of the skin dominate that which is responsible for fair skin
Or
Is it always true that the gene which produces tall plants ( the tall gene )dominate the gene that produces the dwarf plants(dwarf gene)
Or
Is there any chance that in a dwarf plant tall gene being dominated by dwarf gene?
Or
Is it like, only in homozygous state dwarf gene expresses it self otherwise no?
Or
Is it the phenotype which tells us which one is the dominant gene or is there any chance to know which is gene is going to be a dominant gene before it's expression?
Or
what is that which determines the dominance of one gene over the other?
Please clarify my doubt which is a genuine one
Thank you
or
Getting confuse on the word recessive and sex link.so what's the difference?
Thanks;-)
UMM...My mom has Widows Peak and my dad doesn't.I DON'T HAVE WIDOWS PEAK!!!!HELP MEEE!!!! I AM SO CONFUSED
then you got no widows from your dad but in the future your chilrden could have a widows peek because your mom is carrying that ressive trait and if your parnter has a widows peak or hes carrying that as a family ressive trait your child could have one
Ur a defect. Easy said.
it is possible but rare :D
it means your dads genes are stronger
I have a question
Are Amber Eyes dominant or recessive?
You mean brown? Hazel and blue are recessive I believe.
how come me myself a boy by the way, and i have 2 sisters how come I'm the only one who has my mothers nose, head shape, double crown, sleep like my mum, and my 2 sisters have my fathers nose, and have the same trait of how he sleeps
I'm still waiting for an answer if genes are really like the lottery.
my mom has brown eyes and my dad has blue eyes. for some reason one of my eyes is fully brown, and the other one has a little part of it that's green. no one in my family has green eyes so i'm confused why this happened
I have some bad news for you 😂
Nice mam
So can someone be made up purely of recessive traits?? Asking for a friend
I would imagine so. There are a lot of recessive traits and each is inherited independently so the probability would be pretty outrageous:)
I still didn't get what's an allele
But wait, curly hair is a dominant right? Niether of my parents have it yet I do 🧍🏻♀️
What's the difference though???
Thnx
From indiau
it is not understandable for me before this video Thankyou for yourguidance (from Pakistan)😍😍😍😍😍
Green and Brown eyes are the best.
@Mason McCarty green, blue and grey eyes are recessive, it shows a deficiency, they don't even absorb the same high levels of light as brown eyes, also it's likely that blue, green and grey eyes indicate psychopathy in the person who has them.
@Mason McCarty impure how exactly hollow man?
hi sisters!
What if there's two dominant alleles in the pair?
Benzies C
ha
its impossible unless they are the exact same trait. (homozygous dominant)
i have freckles and blue eyes my mum is covered in freckles but doesn’t have blue eyes i thought both parents needed to have blue eyes my dad only has them
@Daniel Fritzsche thanks for the info, my mum actually has green eyes and my older sister has brown eyes, my younger sister has green and my other sister also has blue 😃
Welp. Now I know why Kelly Rowland’s son looks like JayZ.
Thank you so much I have a science final exam tomorrow (I’m in 6th grade loll)
Same as dimples.
I still don't understand how recessive genes can greatly affect a person, just like what happened in every incest relationship. Please explain.
it can affect a person cause if both your parents are O you will be O
I hope this helps a lot
Hideo Kojima brought me here.
But so the dominance or recessiveness of a trait applies to a whole population? That is, is having green eyes a recessive trait? This means that if I have green eyes I must be homozygous for that trait?
can blonde hair go dark brown
Yeah my brother has brown not that dark but darker than average I would say though he had golden hair as a baby and toddler but also I have a cousin which had darker hair as a baby and lightened now but hes still a toddler
is male always the dominant?
elisar bongcales
gender does not influence it.
Yes male genes tend to be dominant.
Yes
I still hope science science develop and bring some solution to increase height
If we have 23 chromosome pairs does that mean that all together we have 46 chromosomes
Im pretty sure we have 23 chromosomes and a chromosome is made up of 2 chromatids meaning each cell has 46 chromatids?
Yes indeed!
what if no freckles is the dominant gene?
Short answer: its not.
Other short answer: than more people would have no freckles and there would be less people with skin cancer.
duhawma does your dad have freckles?
@@ajp.4739 , what's the reason one allele becomes the dominant gene? How is it decided
Thanks this video helped alot
Got stuck reading the selfish gene. Thx
Im nkt really interested in biology but i guess i let you of the hook
Have any social media or email like ask questions pls
Why is a gene dominant or recessive?...
Plz explain us wat is autosomal disease and recessive disease.??...☺
i wish you were my teacher in school im at ps.91
HERC2+OCA2 + melanin
African is strong 🤣🤣🤣
why you think the white man has puts down black people..because they are scared hahahahaa
I have test tomorrow and I didn’t understand 😅😅😅😅
neither of my parents had freckels
i have freckels
whats up with that
and no she didnt cheat
You sound just like Kat Dennings
So say a man with black hair has a baby with a woman who has blond hair. Black is the dominate allele and blond is the recessive so the baby’s hair comes out black. Now say that baby with black hair has a kid with a women with blond hair in the future. What color hair would the baby be??
Great question! Since offspring #1 has one dominant and one recessive (Bb) and the blond has all recessive (bb) their offspring could have either color of hair:)
The answer is Dooominance sorry but that was kinda funny liked the video
I'm studying from India
The real question is how gene become dominant
Aree k bole h sansan
I don't know why I'm watching this or understand it...

on a side note though. I wouldn't mind dominating this teacher 😎

Dude, you're such a douchebag! =_=

can 2 parents have freckles, and the possibility of the child having no freckles? maybe from the uncle
the UNCLE?
the uncle has nothing to do with the reproductive process. but, yes, a child can have the freckles if the recessive gene skips a generation through one of the parents.
I'm not quite sure how genes work quite complex, my sister has a daughter who resembles me, but I am the brother I am not the father explain this?
Well y mom mom has a face full of freckles and i have none
oh well we meet up again Another class for another known teacher teach
one thing that im thinking about is why dose the teacher in our class dosent want to teach us just give us the ... oh now i know why .... hope she gets better soon
Humans don’t have 23 chromosomes they have 46 each
Hand lines are also genetic
Dominant Alleles thats black and brown people.
