Dear Ken,
There aren't any other reference sequences in my analysis besides,
Ventor, Watson, and HUGO. As far as I know these are the only complete Y
chromosome sequences publicly available. I believe that the 132 SNPs I
listed occurred between the ancestor that Ventor and Watson shared in common
(someone in haplogroup R1b1c9) and the ancestor that Ventor, Watson, and the
HUGO R1b1c male shared in common. In other words these 132 mutations must
have occurred on the line from the Ventor/Watson MRCA to the
HUGO/Ventor/Watson MRCA. I believe these SNPs are important to eventually
check in a variety of R1b1c males because I think that they will break R1b1c
(and probably also R1b1c9) into smaller subclades.
Sincerely,
Tim

Did I miss presence of another reference sequence in the analysis? For
instance, could not some fraction (indeed maybe a large fraction) of those
132 mutations have occured on the line from the Hugo/Ventor/Watson MRCA to
Hugo?
