Why it wouldn't matter anyhow
Though Ashkenazi Jews are the largest ethnic group of Jews today, Sephardim (Jews of Spanish and North African descent) and Mizrahim (Jews of Middle Eastern descent) make up the majority of the Jewish population in Israel. Furthermore, Israel has become the home of many smaller Jewish ethnic groups, such as Ethiopian Jews, Yemenite Jews, and Kaifeng Jews. Since the Khazar myth doesn't address those Jews at all, any use of it to prove that "the Jews" aren't real Jews has significant holes.
Furthermore, Judaism has allowed for voluntary conversion through most of its history. Indeed, the great-grandmother of King David, Ruth, was a Moabite convert. Therefore, even if the Ashkenazi were descendants of Khazar converts, they would still be entirely, legitimately Jewish in the eyes of Jewish law.
Additionally there is the question of gene mixing which would inevitably occur when two populations lived close together. No matter how stringent social or religious constraints might be against either, mixed marriages and extramarital sex are still going to happen. An excellent example of this are African Americans that have a much lighter skin-tone than is common in the West-African home of their ancestors. This is of course due to widespread marital and extramarital mixture with non-black populations in the US, and slaves often didn't
have a say in the matter. Thomas Jefferson and his children are just one well-known example of this
[12] Obama's
mother is another good example; it turns out that one of her ancestors happened to be among the first Africans in the colonies and arguably the first slave. And this a result of - at best - four hundred years of living side by side, not twelve centuries as would be the case with the Khazars.
