I don't have the study to which you refer but I have almost 70 Clan
Donald samples of which about two thirds are R1b. I only have one 12 at
461 in R1b,R1a or I. I haven't done a detailed count but 10 appears to
be our mode with a number of 11s and 9s. For my group 461 appears to be
a volatile marker. When I start to get my 25 marker tests back, I will
see how it correlates with 438. I would like to see the Gusmao and
White papers if that is possible.

John,

Good call - I hadn't spotted that. It does look like there is a
calibration
difference of "1" on DYS461.

I have a paper by Gusmao et al (For Sci Int, 135, p150, 2003) of a study

that includes DYS461. Unfortunately those results just muddy the water
even
more. The haplotypes that have DYS438=12 (which should be haplogroup
R1b)
seem to mostly have DYS461=12 - which is different than both the
Relative
Genetics and Cinnioglu's modal result for DYS461. Both Cinnioglu and
Gusmao
cite the paper by White (Genomics, 57, p433, 2003) for their methods
used on
DYS461 - so the calibrations should agree. But it looks like they don't.

So I have to say: "I don't know".

Anybody else have any ideas on this apparent calibration difference?
