YouTube: The Science of Admixture Percentages

The first video from the genetic genealogy sessions at Who Do You Think You Are? Live event in Birmingham is now on YouTube. This presentation The Science of Admixture Percentages by Garrett Hellenthal was given on 6 April 2017.

The first almost 19 minutes are a summary of DNA, autosomal inheritance and matching. Using results from Debbie Kennett and family the video emphasizes the importance of the reference databases. Admixture results refer to best matches to people in the sample, not necessarily where your ancestors are from. More samples will improve results.
