Is This a False Segment?

Segments of DNA that reportedly match can sometimes be pseudosegments, or false segments. These pseudosegments were not inherited from a common ancestor. In this Research Like a Pro with DNA Q&A video, Nicole Dyer discusses pseudosegments and shares an example of finding a probable pseudosegment with a match at MyHeritage. When creating triangulated groups with MyHeritage matches following Jim Bartlett's methodology, you can sort overlapping segments into two groups, one for maternal and one for paternal. If a small segment doesn't triangulate with either group, it could be a pseudosegment. This is because the segment has to be either maternal or paternal.

Nicole Dyer, professional genealogist at Family Locket, shares the answer.
