Ancestral Family Tree DNA Testing / Re: Ancestry's latest Ethnicity update to Ancestral Regions
« on: Monday 14 October 24 08:39 BST (UK) »
I've been researching my background for more than 30 years with several lines back to the 1600s so I have a reasonable idea of where my earlier origins lie. DNA profiles have reflected this in a general way. However the previous Ancestry update very much moved in a negative direction as far as my profile was concerned. Rather than refine my profile it seemed to do just the opposite becoming much vaguer and less informative.
This latest profile though has done much better. It has now taken it back to what I considered more likely before the previous update and refined it rather further - in particular the splits between paternal and maternal now look pretty realistic based on what I know and can speculate on.
Clearly their reference sets keep changing and presumably depending on who that includes not always in any balanced and positive direction...after all it's not a comprehensive DNA census of all living humans. I always download a copy of the profile to ensure it doesn't get lost in the next update.
