Y-chromosomal Aaron - Cohens in Other Haplogroups

Cohens in Other Haplogroups

Behar's 2003 data points to the following Haplogroup distribution for Ashkenazi Cohens (AC) and Sephardic Cohens (SC) as a whole:

Hg:	E3b	G2c	H	I1b	J	K2	Q	R1a1	R1b		Total
AC	3	0	1	0	67	2	0	1	2		76
	4%		1½%		88%	2½%		1½%	2½%		100%
SC	3	1	0	1	52	2	2	3	4		68
	4½%	1½%		1½%	76%	3%	3%	4½%	6%		100%

The detailed breakdown by 6-marker haplotype (the paper's online-only table B) suggests that at least some of these groups (eg E3b, R1b) contain more than one distinct Cohen lineage. It is possible that other lineages may also exist, but were not captured in the sample.
