Hello, I’ve made this account a while back only to read some interesting threads but never actually commented or posted anything. The following may be more suitable for the 23andMe sub-forum to which I don’t have access, but I don’t mind posting this here if it’s alright. So, to get to the point:
Recently, some of my relatives (a parent and two grandparents) took the DNA test by 23andMe (mine is still in the process), and I’m surprised by the ethnicity estimates. The reason for this is a pretty well-researched family tree, based on which all of my known ancestors (8 generations back) were born in what is today Slovenia. 23andMe places Slovenia into the Eastern European region; therefore, I, naturally, expected that to be the prevailing region. In reality, it varies from 65% to 79%. It’s not a small amount, but if I take my family tree into account, it’s lower than expected. The other regions that appear in the estimates are French & German (10–27%) and Greek & Balkan (2–8%). I do have some unknown ancestors in my family tree, but even if I consider them being something different from Eastern European, it still doesn’t align.
I’ve looked at some posted results of other Slovenes online, and they actually weren’t so much different regarding the estimates. Is it maybe just that 23andMe has a certain reference population for Slovenia, which results in this kind of estimates? Does the geographical location of Slovenia being a small country at the crossroads of certain regions make creating estimates more difficult? Probably the main reason for me to begin being somewhat uncertain about the results (and to a lesser extent my family tree) was my friend getting the results. They showed 0% for both French & German and Greek & Balkan, which I — until then — though was common for all Slovenes to get in their report.
If anyone would be willing to help me get more sense of the results, I’d be extremely grateful!
