🤔 Are all your DNA cousin matches worth researching? 👉🏼 kzbin.info/www/bejne/hWrXh5p8orSro80

[@AA-js8yx]

Most cousin couples have healthy children. _But the risks apply primarily to couples who are carriers of disorders that are normally very, very rare, Bittles explained. "For over 90% of cousin marriages, their risk [of having a child with a genetic abnormality] is the same as it is for the general population," he said._

[@Dark-night565]

Thanks ❤

The problem is when marrying cousins has been done generation thru generation... the risk for birth defects will be greater.

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.

My 2nd great grandparents Frank Tilton (1873-1954) and Jenny Clayton (Tilton) (1878-1952) are 7th cousins. I wasn’t that surprised considering that their families are from Monmouth County in NJ and have lived there since the late 1600s. Their most recent common ancestors were John Morford (1623- 1708) and Margaret Morris (1630-1720).

Many families interconnected from small communities. However, it's rare that the couple marrying and having viable offspring for many generations were 1st cousins.

I'm about to marry my second cousin sister,is it ok?

[@kparhow]

Here is a question about the effects of a pairing between first cousins. My spouse has a marriage between first cousins a couple of generations back. After several miscarriages, we had our DNA tested and my spouses came back with a balanced translocation between chromosome 6 and 16 (non-standard karyotype: 46,XX,t(6;16) (q21;q23)). The interchanged pieces involve portions of the long arm of both chromosomes. The same number of SNPs are present, just some are moved to another chromosome. A sibling also has his translocation. We were fortunate to have a child who has a standard karyotype. The questions are: How do the different Autosomal DNA testing companies (Ancestry, 23andMe, etc.) handle the translocation when they process a DNA sample? How does this affect the DNA Matching results?

[@FamilyHistoryFanatics]

I don't know that specifically, but since SNPs are identified because of the adjacent corresponding DNA (which is identical between everyone), I would guess that the end matching results are unaffected.

[@infini_ryu9461]

7th cousins are barely any relation or not something we would call related. You would fit the general public where the risk is about 2%. Entirely unrelated to 7th cousins marrying.

My husband has 4 sets of of first cousins marry within 2 generations, then that branch which I am 97% sure is his paternal grandfathers branch are also married into his paternal grandmothers branch and just to make it interesting there are a couple of his maternal grandmothers branch married in for fun.

I'd be interested to know what the source of this statistic that 80% of marriages in history were between 1st or 2nd cousins. I don't know whether this is skewed to one region or another, or one era or another, but certainly from my ancestry, predominantly in UK and Ireland back to 17th century, cousin marriages were very much in the minority.

[@melvawages7143]

what I have found for the most part in my father's family who came from a small rural community in Mississippi was not that they married their cousins but cousins on his maternal side were also related to cousins on his paternal side. For example, my paternal grandfather and his 1st cousin married sisters. That means my father had maternal first cousins who were also his paternal second cousins. They did try not to marry close relatives. My grandmother did have one brother who married their second cousin once removed. both of his children were born with health issues. One son was legally blind and the other son had one leg shorter than which my grandmother believed was because they were cousins.

[@melvawages7143]

but the only real issue this causes is when an adopted person who shares your DNA as 2nd to 3rd cousin and you are trying to pin from where. I know she matched my father's side of the family but I do not know how since she matched both his paternal and maternal cousins.

[@kassandralanda1062]

You could marry anyone as long as their not close relatives.. 1st cousins are like boarder line of being okay and after that like 2nd 3rd 4th it doesn’t matter, your able to marry …

[@staceycoates1418]

I agree that there is nothing wrong genetically with marrying a first cousin today. But I think that taboo came out in the time where first cousins who marring were coming from a set of first cousins who had married and maybe those grandparents were first cousins too. I think then you are more likely to inherit genes from that 5th great grandparent and that could lead to a higher chance of birthdefects. But for the last century at least families have shied away from cousin marriage so I think now there is a lot of 'fresh blood' as far as genealogy playing a factor in birth defects. To use myself as an example; I am a European mutt. I have no pedigree collapse and every branch I can take back to at least 1850. My family has branches that came over any time from the late 1600's to the 1880 and from various places in Europe. If I would marry a hypothetical 1st cousin (my uncles did not have any biological children so hence the hypothetical) that would be a factor. And while I may be unusual with how far back I have gone without finding pedigree collapse in my direct line but I think that there are a number of people who can go 100 years until they find it.. Actually, that makes me think of a question. What is the average number of generations that someone has to go back to find pedigree collapse? If I look at a 6 generation pedigree chart with me a the point there is no collapse. And after that I start having some drop off because they were born in England and immigrated as a family with a young son, not with parents.

[@FamilyHistoryFanatics]

Great question, maybe I can put a poll up for people to answer.

[@ayf3056]

Hi, I support cousin marriages! I'd like to know if there is an organization to help spread the good news that cousins can marry without it being discouraged in societies in our cultures. Second, since the only issue is that of genetic inheritance, is there a genetic test that is encouraged for first cousin? In reality, most couples that are not related don't test for this and they do pass down genetic disorders or diseases. Can you imagine how cruel it is to not marry someone because they have diabetes or cancer? When you love someone, you love that person "in sickness and in health."

I think you’re too quick to dismiss the dangers of marrying a cousin. I think anyone contemplating marrying a cousin should go for genetic counselling, though a one-off situation is probably not a great danger, however, some communities inter-marry a great deal. Communities that practice cousin marriage have higher numbers of children with inherited conditions. Here in the UK, the Pakistani origin community has the highest level of cousin marriage and a higher proportion of children with inherited conditions. Because you have people who are the products of cousin marriages going on to marry cousins themselves.

Thank you for this video, I want to ask What do you think of the marriage of "double" cousins (cousins whose fathers are brothers and mothers are sisters)?

[@FamilyHistoryFanatics]

I don't think anything of it from a moral stand point. However, a person marrying their double first cousin will definitely run the risk of negatively impacting the genetic code of their offspring similar to what I said in this video.

[@mmaman6931]

What about marrying cousins in successive generations? What are the stats on that?

I'm not entirely sure. It does complicate genetic genealogy research.

Hi Family History, I have ordered AncestryDNA Kit and I'm wondering is it possible to take the required amount of saliva from 2 years old kid? What is the minimum amount needed to perform the test and is there any other materials they accept like hair? I did not open it yet and if it not possible then I'm going to return the kit. Thanks.

[@FamilyHistoryFanatics]

For Ancestry and 23andMe, the kid needs to be able to spit. I've had a 6 year old do it but haven't tried with a 2 year old. Its not a lot of spit, probably about 10 good spits. Family Tree and MyHeritage use a cheek swab which would be easier to get from a small child. No one accepts hair.

there's always a chance that your genetics will pass down negative mutations. However, as explained in the video, it's the more closely related relatives that have more genetic issues in their off spring.

[@bimmerhuncho908]

2% for everyday couples that are strangers & 4% for 3rd Cousins. That means that your kid will have a 98% chance to be absolutely normal vs 96% with 3rd cousin. That is hardly a difference stats wise!

[@FamilyHistoryFanatics]

A half sibling shares around 1700 cM. But in your case, with your paternal grandparents being 1st cousins, you would expect more shared DNA, around 2000 cM. But the range is probably between 1600 and 2400. So there is some overlap between normal half siblings and full siblings. It is probably going to be reported as an aunt/uncle, grandparent, or grandchild, and possibly a sibling.

You can marry anyone that your country's laws allow. The question to consider is whether this would be detrimental to your offspring or not.

I think opposites attract is based on the phenomenon of not sharing two recessive genes. In other words, if you're attracted to your cousin, theres probably a good chance you are not going to have mongoloids as my parents used to say.

[@infini_ryu9461]

The opposite is true. Sharing things in common is true. It is very likely teo siblings that never got to meet until later in life start romantic relations. 3rd and 4th cousins have been shown to have the healthiest offspring with the most grand children. Expect to see more miscarriages as people lose their minds over avoiding even 5th cousins. We are all cousins.
