Studies on Jewish genetics have clearly demonstrated two things. First,studies of the Y-chromesome have shown that Jewish populations the world over are still genetically semitic,and are almost indistinguishable, genetically at least,from other middle eastern populations. Granted,the study found that Mizrachim and Sephardim were closer than Ashkenazim to the middle eastern populations, but it was not a large margin of difference.
The second thing that the studies demonstrated, in looking at mitochondrial DNA,which gets passed from mother to daughter (as opposed to the Y chromesome, used for the first part, which gets passed from father to son), is that its genetic material is much closer to the host population`s than is the Y chromesome. The conclusion they drew was that when Jews spread out from Palestine,the males would often times mate with local females,and therefore the Jewish populations outside of Palestine eventually gained an appearance like that of their host populations. |
