Researchers find no indication of Khazar genetic ancestry among Ashkenazi Jews

Employing a variety of standard techniques for the analysis of population structure, scientists found that Ashkenazi Jewish samples share the greatest genetic ancestry with other Jewish populations, and among non-Jewish populations, with groups from Mediterranean Europe and the Middle East, and that they have no particular signal of genetic sharing with populations from the Caucasus. Thus, analysis of the most comprehensive set of Jewish and other Middle Eastern and European populations together with a large sample from the region of the Khazar kingdom does not support the hypothesis of a significant contribution of the elusive Khazars into the gene pool of the Ashkenazi Jews.
