* As shown above, the Y-DNA frequencies set forth herein are largely consistent with those reported in: (1) a 2004 paper, D. Behar, et al., Contrasting patterns of Y Chromosome variation in Ashkenazi Jewish and host non-Jewish European populations, Hum Genet (2004) 114:354-365, which reported the above frequencies of Y-DNA haplogroups among Ashkenazi Jews based upon a sample of 442 men (results from different clusters within haplogroups in the Behar paper are combined); and (2) calculations based on the 519 Y-DNA branches, comprised of 2,730 sets of STR marker values, compiled by Wim Penninx for his Catalogue of Y-DNA Jewish branches (including Ashkenazi, Sephardic, Mizrahi, and Samaritan branches) posted on his website, JewishDNA.net, based upon his painstaking compilation and analysis of Y-DNA results gathered from FTDNA project pages and YSearch.org.

** As of 2003, what is now Y-DNA haplogroup T was part of Y-DNA haplogroup K

Wim Penninx's website, JewishDNA.net, provides a pie chart that sets forth the distribution of Ashkenazi Y-DNA branches, ordered by size.
