Dear Gareth,
Thanks for your insights into this situation. This likely explains
the cluster of 14 SNPs in the 12933864-13681909 position region as below
that Watson and Ventor share.

12933864rs9786460
12934053rs7892854
12942936rs2740980
12943108rs2740981
12979419rs2713254
13032836rs11799149
13151202rs13304168
13184196novel
13211040rs7892925
13373585rs7893052
13465511rs35108305
13499115rs9786537
13595577rs7067251
13681909rs11799198

To be conservative, it would appear that it would be best to
consider all of these except for possibly the novel one above to be from a
non-R1b1c male. This would reduce the 132 SNPs that Watson and Ventor share
relative to a revised R1b1c HUGO Reference Sequence to 118 SNPs. It will be
interesting to see how the WOY project progresses and to see which section
of the Y chromosome that Thomas Krahn chooses for the first phase of the
project.
Sincerely,
Tim

Further to this, following up the references in the paper below, AZFa
appears to be approximately bases 12942302 (start of STS sY746) to 13743639
(end of STS sY1066).

The following recent paper from the same lab looks interesting, especially
figure 1 which gives locations of various features of the Y chromosome with
the current reference sequence numbering:
