Please help! In Wikitree. There are people, they brag about their Phds and all. Keep telling me I am not a real genealogist. I have been working on my family tree stuff for a long time. I have been able to work off of what has been handed down from generations going way back. There is one part of my family tree that someone puts in this big long spill about DNA, because they have DNA connecting two or three people, the other people in this family tree they don't have DNA matches for or something about they are not part of some certain DNA group. These people will tear that/my family tree apart. Adding other people, deleting people, and so on. It is like they use the DNA as a way to bully me out of certain parts of my family tree so they can twist their family tree into it. My question is how can it be 100% positive there are DNA matches for people 200 plus years ago? My understanding is that DNA is only as good as the data that is reported, such as family histories.

Thank you very much Andy Lee for clarifying a complex subject. JK Esq.

Question: on Ancestry it show no match with a dna match for Gedmatch that I test at 100 SNP 5cM with all the B36 B37 B38 selected which showed matches from 9 chromosomes matched twice on 12th Chromosomes Chromosome 3 Chromosome 8 Chromosome 10 Chromosome 12 Chromosome 13 Chromosome 16 Chromosome 22 Did that test bySNP 100/ 5cM to get the MRCA generation: at 6.1 Total Half Match segments (HIR) 46.9cM Estimated number of generations to MRCA = 6.1 Largest Segment 7.4cM 8 shared segments but in the tree on FamilySearch where meant to be 12th cousin twice removed where is does show they married cousins and generations before them too is this how it is showing no match on ancestry matches

Just had a panel, read my results. HIV Negative, Syphilis Negative, ABO type O, RH factor Positive. Me an idiot: "Oh no, I have RH factor" Doctors, please put RH factor in a different section than blood born diseases. It took all of 20 seconds to realize that just meant I'm O+ and don't need to call past girlfriends. But man, what a 20 seconds.

I found out through a DNA test that Benjamin Franklin is my 8th great grandfather. Surprised me

What’s the mega base length of a second cousin? In terms of roh

We have *23* chromosomes from each parent, not 22.

Lost me at the other jew

Too bad that option isnt available anymore

is it ethnicity or regional origins?

Weird but very disheartening.

You are so right! Thanks for helping us better understand new ways to use this data! MyHeritage provides really good segment matching data, so I downloaded segment data for more than 200 matches, down to about 40 cM (I got lazy at that point). In some cases, overlapping matches really help with assigning segments to a specific ancestor. Even this great level of this information leaves some ambiguity, unless you match the exact same RSID, because you have two of each chromosome. But it sure can help to direct your attention to a fruitful area. It's like their one-to-many browser, but for your top 200 matches. Since it sorts by location, for each chromosome, all of the overlapping segments are gathered together. There's no particular limit to how many it can represent, but it does get tiresome downloading that data one match at a time. After downloading the csv files, though, the process is automated.

My real last name is Jackson but I don’t know who am I related to

So you will never really know from where your grandparents reqlly came from

I did 2 with 2 companies. They all essentially overlapped and matched what I had been told. One said I had Canadian blood. My great-grandfather was from Canada. Also, it declares I have German blood. My great-grandmother was born in Germany. The rest is pretty much British/Irish, which matches all the family tree research. The only odd bit is it says I had relatives on the border of France/Spain, some in Eastern Europe (Russia?) and 4% in Africa. The Africa I don't know, could be primordial Eve. But, the European makes sense.

Wouldnt want to have a dna test sent to some dodgy company and then uploaded to the internet

Hello I made a list of my matches 90cms to 400cm I have got two colums worked out There are two people in my list of matches that when i run their matches with me the result is matches below 90cms. So i have only ended up with two colums with people in. Do i go below 90cms with them Thanks Pat Berry

What is the litmus test you use to compare say... "Dubliner DNA" to a sample? The fact that you'll get four different answers from four different companies testing pet DNA tells me nobody really knows what they're doing. Especially considering human ancestry is more complicated than dog breed ancestry.

Additional information for anyone interested. When cousin marriage is practiced over six generations, the genetic risks continue to compound, further increasing the likelihood of genetic disorders. The inbreeding coefficient becomes significantly higher, leading to a greater probability of inheriting harmful recessive genes. Understanding the Inbreeding Coefficient The inbreeding coefficient (F) measures the probability that an individual has two identical alleles at a given locus because of shared ancestry. For first cousins, this coefficient is 0.0625 (6.25%). Compounding Risks Over Six Generations First Generation (F1): First-cousin marriage, F = 0.0625 (6.25%). Second Generation (F2): If children of first cousins marry first cousins, F increases roughly to 0.125 (12.5%). Third Generation (F3): Continued cousin marriage, F ≈ 0.25 (25%). Fourth Generation (F4): Further cousin marriage, F ≈ 0.5 (50%). Fifth Generation (F5): The inbreeding coefficient continues to rise, and can approach but not exceed 1.0 (100%). Sixth Generation (F6): The coefficient becomes very high, often leading to a critical level of homozygosity for deleterious genes. Genetic Risks Over Six Generations Each generation of cousin marriage increases the risk of genetic disorders significantly. Here’s a more detailed look at how risks might escalate: First Generation: Risk: 4-6% for genetic disorders. Second Generation: Risk: 8-12%. Third Generation: Risk: 12-20%. Fourth Generation: Risk: 20-30%. Fifth Generation: Risk: 30-40%. Sixth Generation: Risk: 40-50% or higher. Key Points Increased Homozygosity: The repeated cousin marriage leads to increased homozygosity (having identical alleles at a gene locus), making it more likely for harmful recessive genes to express. Cumulative Effect: The cumulative effect of inbreeding over multiple generations significantly increases the risk of recessive genetic disorders, congenital anomalies, and other health issues. Examples of Potential Disorders Recessive Genetic Disorders: Disorders like cystic fibrosis, sickle cell anemia, and Tay-Sachs disease. Congenital Anomalies: Heart defects, neural tube defects, and cleft palate. Intellectual Disabilities: Various forms of developmental and intellectual disabilities due to genetic abnormalities. Mitigation Strategies Genetic Counseling: Families practicing cousin marriage over multiple generations should seek genetic counseling to assess risks and make informed decisions. Genetic Testing: Pre-marital and prenatal genetic testing can help identify potential risks and enable early intervention. Diversification of Gene Pool: Marrying outside the family can help diversify the gene pool and reduce the risk of genetic disorders. Conclusion The practice of cousin marriage over six generations dramatically increases the genetic risks due to the compounding effects of inbreeding. The inbreeding coefficient rises significantly, leading to a higher probability of inheriting harmful recessive genes and a greater likelihood of genetic disorders. Genetic counseling and testing are crucial to managing and understanding these risks.

I found all three of these ancestry sites have given me the same results within two or three percentage points

The problem is giving DNA national identities like French or English. Really they should just show you where your markers were found and what general race you are. BUT your eyes are the best indicator of who you are. My eyes tell me you are a white european. End of.

Wouldn’t those 120 be among our more recent ancestors?

Your percentages are really assuming that peoples 5 generations back are racially pure too no? A lot of folks were multicultural and nowhere near racially pure. This includes folks from around the Mediterranean and Asia Minor (who were members of those really large empires: Roman, Achaemenid Persian, and Byzantine). The Mongolians too were taking women as war prizes and carrying peoples across Northern Asia. I just watched a Japanese girl surprised that she had Finnish blood. Mongolians were in Kieyvan Rus in 1240s, then attacked Japan in 1270s. The Persians and Middle Easterners did this to the Scythians too.

Oh😮

I'm part Hikawi Indian

Interesting how my sister had Iceland circled as a country with her genes. The TRUTH is, Iceland was founded by viking men and their irish wives. HOWEVER my mother is heavily Irish and 8% Swedish presumably from the viking settling in Ireland. Blue eyes in A LOT of her family. We had to laugh that she has 0% English. Didn't expect that.

I have a source it is my Great-Grandfather's obituary. This source is listed as unfinished Also, the people in the obituary are listed with their own obits. The PID is KGC8-1PD and continues through his grandchildren. HELP

However, it must also be taken into account that if nine chiasmata occur in a chromosome, it is not necessary to consider exclusively one of the two sister chromatids that make up the chromosome but rather both, therefore those nine chiasmata could be six in one sister chromatid and another three in the other arriving thus to nine chiasmata on chromosome number two. We must also take into account the interference of the first chiasmata and therefore it becomes normal for the other chiasmata to occur in the other sister chromatid.However, it must also be taken into account that if nine chiasmata occur in a chromosome, it is not necessary to consider exclusively one of the two sister chromatids that make up the chromosome but rather both, therefore those nine chiasmata could be six in one sister chromatid and another three in the other arriving thus to nine chiasmata on chromosome number two.

what is the difference between X Chromosome Triangulation and autosomal triangulation?

Family Tree 10 - you have to pay for it but you link it to Family Tree and you have a copy that DOES NOT CHANGE UNLESS YOU DO SO!! This way if someone does something like that - you can literally go into the profile under sync and reupload all of your original information

Scots ur grate fuckers😂😂😂

I have over 62,000 matches

I'm a Homosapian

I have Blue eyes and no wrist bone.

First time

Stop saying that person. Because its more likely that person's children or grandchildren that migranted to a new area.

The Americas aren't the last to be inhabited. It goes back to 32k years ago

Does chromosome duplication, show up in results that are transferred from MyHeritageDNA to MyTrueAncestry Civilization heatmap as my 19 yr old Son’s chromosome 7, 8, 21 aren’t shown but the thing is it’s only known He has Chromosome 7 as a duplication, as he had a blood test done for a genetics test 🧬 just wondering why they chromosomes aren’t showing where he received them, as it show I received mine from Viking Danish and Viking Norwegian, hoping this is something your able to answer, as watch most of your videos 💛

I had my autosomal run and wonder how I got Mayan DNA.

Thank you for the lesson, sir. Super-useful

These are the pillagers and slave masters

I’m Haplogroup R-CTS11567. I don’t know much about it.

As a Puerto Rican, I was not surprised to find I’m 100% mutt. I thank all my ancestors for enduring their journeys through life so that I was able to exist❤

I put a relative on by mistake and can't find how to erase them????

Really really interesting, I have been researching my family for years in what has obviously been a very amateurish way, but I don;t know where to begin to fix this.
