Short Summary: Before the end of the year, AncestryDNA plans to update our match lists using a new algorithm that reduces the number of false positive matches. For the first time, matching DNA segments will be characterized as IBS (i.e., a false positive) based on something other than simply segment length.
Last Monday, October 6th, I and six other members of the genetic genealogy community attended a ‘Bloggers Day’ hosted by AncestryDNA at the San Francisco headquarters of Ancestry.com. Two other members of the group have already written about the event:
- When less is more – The Legal Genealogist by Judy Russell
- DNA Day With Ancestry – DNAeXplained by Roberta Estes
While at ‘Bloggers Day’ we discussed many issues including the Y-DNA and mtDNA databases originally scheduled for destruction, upcoming changes to AncestryDNA’s matching algorithm (much more below), and other upcoming changes to the AncestryDNA about which you will hopefully soon hear much more.
