In that file, under “Is It Accurate,” for example, provides the following: When determining your genetic ethnicity, we hold our process and results to an extremely high standard of accuracy.Our lab’s analysis uses some of the most advanced equipment and techniques to measure approximately 700,000 points in your genome (with at least a 98% rate of accuracy).
I’m not sure whether the Ancestry DNA tests these 700,000 SNPs, or whether it tests more SNPs but is currently using a subset of 700,000 for its analysis. I thought it might be interesting to compare my genetic ethnicity results from the three companies (Ancestry.com, 23and Me, and FTDNA): After reviewing the results one thing is certain: all three companies estimate a strong European contribution to my genome, particularly Scandinavian (ranging from 68% to 78%).
It’s ironic, however, that I have yet to identify a single Northern European ancestor!
I certainly won’t be surprised when one pops up someday.
Clicking on “See Full Results” takes me to a more detailed analysis of my ethnicity results, but not before I click through the following pop-up: Please keep in mind…Our prediction of your genetic ethnicity is not yet finalized.
Today, I’m reviewing the new autosomal DNA test from called “Ancestry DNA.” I’ve already written at length about Ancestry DNA, so I won’t cover too many of the basics here.
I have an in-depth introduction to the product located at “Ancestry.com’s Ancestry DNA Product,” which you might want to check out before or after reading this review in order to gather more information.
Ancestry DNA: An Introduction The introduction page, which appears after clicking on “View Results” on the front page, consists of my Genetic Ethnicity Summary and the Member DNA Matches (which is further broken into close cousins and distant cousins, as discussed in detail below).
Please note that for purposes of this review I’ve removed the identifying information for my genetic matches.
Genetic Ethnicity Summary: My genetic ethnicity results, which suggest 90% European and 10% Uncertain, are very interesting.
In a recent webinar with the Ancestry DNA team, they reported that the genetic ethnicity analysis is still very early in the beta phase, and will continue to be updated and refined as new reference populations are added.
Indeed, I’m predicting that over time as new information is added and the algorithm is refined, some or all of my10% Uncertain will be categorized (perhaps to reflect my maternal Asian and African contributions, which I’ve written about before), and that some of of my 90% European may very well change.
