Some genetic genealogists and genealogists pan genetic ancestry or ethnicity admixture estimates. They see them as not useful and wouldn't mind if ethnicity predicting was discontinued. On the other hand, I see genetic ancestry estimates as part of the genealogy cycle of life.
I understand that matching to genetic relatives is a natural progression from traditional genealogy methodology and practices, but genetic ancestry estimates are a natural extension of DNA relative matching and both can be used synergistically to achieve optimal results.
I'm sure by now you've seen or heard about 23andMe's new Recent Ancestor Locations feature added to its Ancestry Composition tool or last year's AncestryDNA Genetic Communities included with its Ethnicity Estimates—each touts unprecedented granularity with genetic ancestry estimates and addition of over 100 regions or reference populations.
Thus 23andMe ($99 US; $199 w/Health) and AncestryDNA ($99 US) have figured out a way to make their ethnicity admixture tools more relevant by "marrying" genetic ancestry to our genetic relatives! Both DNA testing market leaders have been able to achieve this matrimony by "fine-scaling" their respective ethnicity admixture offerings, which I will review for this blog.
- PINK ELEPHANT IN THE ROOM: On May 11, 2018, 23andMe hit AncestryDNA with a patent infringement and false advertising lawsuit [see here]. Based upon the bones of the case my analysis may seem to implicate a party. However it's unintentional as I've been working on this blog prior to the lawsuit. I hope the legal issue is amicably resolved between the parties.
