The genetic variation in the R1a clade among the Ashkenazi Levites' Y chromosome.

ABSTRACT: Approximately 300,000 men around the globe self-identify as Ashkenazi Levites, of whom two thirds were previously shown to descend from a single male. The paucity of whole Y-chromosome sequences precluded conclusive identification of this ancestor's age, geographic origin and migration patterns. Here, we report the variation of 486 Y-chromosomes within the Ashkenazi and non-Ashkenazi Levite R1a clade, other Ashkenazi Jewish paternal lineages, as well as non-Levite Jewish and non-Jewish R1a samples. Cumulatively, the emerging profile is of a Middle Eastern ancestor, self-affiliating as Levite, and carrying the highly resolved R1a-Y2619 lineage, which was likely a minor haplogroup among the Hebrews. A star-like phylogeny, coalescing similarly to other Ashkenazi paternal lineages, ~1,743 ybp,
