I have not seen any distinction among Jewish subpopulations in
admixture analysis based on autosomal DNA tests. My Family Tree
DNA results indicate 100% Middle Eastern (Jewish). My ancestors
all came >from Europe, half of them Ashkenazi and half Sepharadi.
The admixture models are a work in progress and should be taken
with a big grain of salt. They are constantly being refined and
changed based on the self-reported ethnicity of people who are
tested, and on ancient DNA samples that continue to be analyzed.
Many people have complained about inconsistent results. For
example, a person may be reported one week as 100% British Isles
and the next week the same company's report says he's 50%
Scandinavian.

I have also uploaded my DNA file to gedmatch.com. They offer
several different admixture models with about a dozen variations.
Each model variation gives different admixture results.

Debbie,

All of you are probably Ashkenazi Jews and your DNA analysis did
not change. It is FTDNA that changed its designations.

According to FTDNA:
One of my sisters is 100.00% Middle East (Jewish)
Another sister is 99.37% Middle East (Jewish) +/- 0.77%
I am 85.21% Middle East (Jewish), 14.79% Europe
We all have the same father and mother. I just ended up with a
little more distinctly non-Jewish European genes.

23andme told me that I am 94.8% Ashkenazi. When I delved for its
world placement they told me 99.9% European and .1% unassigned.

The difference between FTDNA's and 23andme's formulations is
ideological.

Anne Wojcicki places our origins in Europe, while Max and Bennet
affirm our west Asian roots.

Dear DNA'ers,

Can anyone refer me to a detailed article about the DNA difference
between Ashkenazi, Shaphardic, and Mizrim Jewdisim? My mothers
autosomal test first showed 100% Ashkenazi, and was then changed to
100% Middle Eastern Jewish. My fathers first cousin's autosomal test
came back 100% Middle Eastern Jewish.

Thank you.
