The double figure is because SMGF reports DYS385a and DYS355b
individually, and also as a pair. Pairwise there are 2*(33053) alleles
(samples) ...

> Ken - I haven't communicated with SMGF personally on this issue. SMGF has posted statistics on the Y-Chromosome Marker Details page of its website for everyone to see. Details are displayed for both DYS385a and DYS385b, which show two apparently-independent "grand totals" of 33,053 and 66,106 samples respectively. I was discussing the latter, where 29/66106=0.00044 - the rounded frequency that SMGF shows for 13.2 at DYS385b. But your observation is correct. The latter figure is precisely twice the former, which is unexplained. Charles
