There is a genetic connection between most Jewish communities worldwide and the eastern/southern mediterranean region. But this is a very large area. It includes what is today Israel, but it also includes Lebanon, Syria, southernTurkey, Greece, North Africa and even southern Italy. About 70% of Ashkenazi Jewish males have Y chromosomes of haplotype J (modal Cohen) and E1b1b1, which are different from haplotypes R1a, R1b and I that are dominant among central and eastern Europeans. However, the J and E1b1b1 markers reach similarly high proportion in Greece and Sicily. Therefore, a lot of the ancestors of modern day Ashkenazim could have been converted Roman citizens from this broad mediterranean region but not from the biblical Judean area. Therefore, genetic data does not disprove Sand's contention.
