DNA has unlocked countless genealogical mysteries. You can listen to this episode by clicking the play button below. Length: 13 minutes. Just like people start doing genealogy for a variety of reasons, people take DNA tests for different reasons. Some people who take an DNA test are only interested in the ethnicity estimate. But I have to say that I’m ok with people who take the test just for the ethnicity estimate.
When Cousins Get Married
Couples who are third or fourth cousins tend to have more kids and grandkids than other couples. And though considered somewhat of a cultural taboo, mating between “kissing cousins” makes good biological sense, say scientists. The findings, which come from a recent study of Icelanders, shed light on how relatedness affects reproduction and ultimately the size of families. The researchers suggest marrying third and fourth cousins is so optimal for reproduction because they sort of have the “best of both worlds.
The study also has implications for population growth in a world that’s becoming more and more urbanized.
The more of this they find, the more closely related two people are. For example, for your 5th cousins, only 1/th of them will share your.
But what is the proper term for said distant relatives? It can be confusing trying to figure it out. If your closest relative is a great grandparent, but there is one generation gap, are you third cousin? Are they removed? The further back the first common ancestor is, the larger the number. First cousins are as close as you can be and still be cousins. It means that the closest ancestor that two people have in common is a grandparent. If they were any more closely related, they would be siblings.
Third cousins, then, have a great-great-grandparent as their most recent common ancestor. Their most common ancestor might be the great-grandfather of one and the great-great-grandfather of the other. In the example below, John and Mary had two sons: Adam and Abe. Barbara and Bob are first cousins. Their closest common ancestors are their grandparents John and Mary.

Performed the experiments: LH. Analyzed the data: LH. Although a few hundred single nucleotide polymorphisms SNPs suffice to infer close familial relationships, high density genome-wide SNP data make possible the inference of more distant relationships such as 2 nd to 9 th cousinships. With data from populations, we show that the average amount of DNA shared IBD in most ethnolinguistically-defined populations, for example Native American groups, Finns and Ashkenazi Jews, differs from continentally-defined populations by several orders of magnitude.
Using these bounds as a guide, we detected tens of thousands of 2 nd to 9 th degree cousin pairs within a heterogenous set of 5, Europeans. The emergence of genotyping platforms that assay hundreds of thousands of sites across the genome has facilitated the rapid growth of databases with genome-wide data for human populations  — .
Can You Marry Your Cousin?
In modern western society, marrying your cousin is not well accepted, particularly in the United States. Through a combination of old prejudices and present-day conventional wisdom about inherited birth defects, first cousin marriage is seen by many as a little too close for comfort, as well as a bad idea if you want children. Further, if you include second cousins in the mix, according to the Clinical Genetics Handbook , the increased risks with regards to having children are nearly non-existent in this case compared with non-cousin marriage.

I learned a ton about my four paternal great-grandparents—again, I had known the basic info about them, but it was the details that for the first time made them real people.

This particular genealogical adventure led me to world traveler, writer, and book-reviewer, my 5th cousin once removed, Victoria Weisfeld. While viewing my 23andme matches, I noticed Vicki had taken the time to attach a short genealogical bio.

What does the Bible say about? I am the Lord. You shall not uncover the nakedness of your father, which is the nakedness of your mother; she is your mother, you shall not uncover her nakedness. You shall not uncover the nakedness of your father’s wife; it is your father’s nakedness. You shall not uncover the nakedness of your sister, your father’s daughter or your mother’s daughter, whether brought up in the family or in another home.
You shall not uncover the nakedness of your son’s daughter or of your daughter’s daughter, for their nakedness is your own nakedness. You shall not do as they do in the land of Egypt, where you lived, and you shall not do as they do in the land of Canaan, to which I am bringing you. You shall not walk in their statutes. You shall follow my rules and keep my statutes and walk in them. I am the Lord your God. You shall therefore keep my statutes and my rules; if a person does them, he shall live by them: I am the Lord.
You shall not uncover the nakedness of your father’s brother, that is, you shall not approach his wife; she is your aunt. Or do you not know that the unrighteous will not inherit the kingdom of God?
