I’ve received a number of emails and comments (see, e.g., here) complaining about Ancestry.com’s new test, AncestryDNA. Specifically, several test-takers believe that the Genetic Ethnicity Prediction provided by Ancestry.com does not reflect the numbers that they expected based on their own research.
For example:
“I just got my DNA test results back from Ancestry.com and I am concerned. I was born in England and I have gone back many generations and have found that all my ancestors as far back as the 1600′s in most cases are English. According to the results I have no British Isles DNA. It states that I have 60% Central Europe, 30% Scandinavian and 7% Southern Europe. I also have 3% unknown. How can this be?”
“Just received my results: 21% Southern European and 79% Central European which doesn’t follow years of work on my family history.”
Do these comments reflect errors in AncestryDNA’s Genetic Ethnicity Prediction, or are there other factors at play?
