    I enjoyed the webinar. Although I am not a newbie to autosomal DNA, I am certainly no expert. I have often wondered why my DNA ethnicity was being updated, so Blaine’s discussion on how the use of reference populations determines ethnicity, and that this is still just an estimate. Additionally, it’s fascinating to discover there is genetic variation from our siblings’ DNA, which is passed down from our ancestors.
