Notably, when I only removed segments smaller than 5 cM, I had 212 matches (8.5%) that shared more than 1 segment of DNA, and they broke down like this: It will be interesting to see this analysis from people that have endogamous backgrounds. Interestingly, this might be a way to identify people that come from endogamous populations, but may not know it. Of course these numbers will vary from person to person, and will vary significantly in endogamous populations. It is even more rare to have more than two segments, with just 8 people (<1 %) sharing 3 or more segments. Thus, among my matches, it is extremely rare to have a non-targeted test-taker share more than a single segment of DNA (only 2.5% of my matches). Of those 63 matches, IВ share multiple segments with the following breakdown: Accordingly, I share a single segment of DNA with 97.5% of my 2,491 matches at Family Tree DNA. I share more than 1 segment of DNA with 63 matches, or 2.5% of my matches. This is perhaps the most controversial aspect of this analysis, but see вЂњ Sharing Large Segments With a Match Does Not Validate Small Segments Shared With That Match.вЂќДЄfter I removed segments smaller than 7 cM, I shared a total of 2,554 segments of DNA with my 2,491 matches. I downloaded my list of total shared segments, and removed all segments smaller than 7 cM (these segments are either too small to be valid or too old to be genealogically relevant).

These close test-takers would skew the data.ДЄfter removing them from my match list, I have a total ofВ 2,491 matches at Family Tree DNA.ДЇamily Tree DNA also allows you to download a list of all the segments you share with your matches: I downloaded my list and removed all of my targeted test-takers (anyone that I tested or I asked to test). I wanted to have better data to cite, so I took a closer look at this issue.ДЄt FTDNA, you can download a list of all of your matches: I usually say that we share a single segment of DNA with 99% of our matches, but thatвЂ™s been an off-the-cuff estimate. I have told people in the past that we share a single segment of meaning IBD DNA with the vast majority of our genetic matches (where IBD means Identity-by-Descent, or a valid matching segment of DNA from a recent genealogical relationship).
