The studies have long since been done. About 38% of Palestinian have the Hebrew J1 haplotype. Only 16% of the Ashekenazim are related to the ancient Jews. About 59% of Negav Bedouins have the ancient Jewish DNA, and about 76% of the modern Yemeni are also related to the ancient Jews. I am related to them, and am not Jewish, as are many non-Jews. My husband is Jewish and not related. The Sephardim and Mizrahim are more closely related than are the Askenazim. I don't remember HOW many have the J1 haplotype, but, I can look it up is anyone is interested. The lesson is, there are no genetic straight lines after millenia.
