This lecture will discuss how best to weed out false-positive DNA Matches that test-takers from endogamous groups face daily. Alec will outline the data (both peer-reviewed and crowd-sourced) that demonstrates the unique ways in which endogamous populations match each other. Then, by using visualizations such as RootsFinder, DNA Painter, and Genetic Affairs (or whichever tools are most useful at the time of broadcast), he will illustrate webs of interrelationships of endogamous test-takers and identify genetic pile-up regions. Although there is no surefire method as of yet to remove false matches, by having a better understanding of endogamy, we can better analyze match data.
