ujm, I was quoting from memory genetic testing results I read about that looked pretty reasonable – Ashkenazim came from a small community of Jewish men. Sephardim are pretty diverse. This would be, I think, in contradiction with Khazar theory.
does it contradict your mesorah? which part of my statement?
1) diversity of Sepahrdim? depends whon we call S. I fthose who were in Spain, then they might have all come from the same place. But we nowdays call every non-A a S, including Persians, Yemenites
2) small group of first men Ashkenazim? what are other views? Note that there might have been more at the beginning, just not all had surviving einekles
