I am simply following the Watson/Ventor/HUGO R1b1c male SNP trail
where it is leading us. I agree that we should in general be avoiding
heterochromatin. I don't know exactly what is in the region from position
57392694 to 57440935, but Watson, Ventor, and the HUGO R1b1c male do seem to
have quite a few SNPs that they share in that region. This region doesn't
appear to be heterochromatin or it wouldn't have been sequenced for Watson,
Ventor, and the HUGO R1b1c male. Thomas Krahn's Y browser indicates that
there are some genes in this region such as "C-terminal binding protein 2

I'm surprised by the locations of some of the SNPs in your list.
Shouldn't we only look in the "Male-Specific Y" (MSY) regions and portions
that are not heterogeneous chromatin? Gareth gave a recent reference to a
useful paper, "MSY Breakpoint Mapper, a database of sequence-tagged sites
useful in defining naturally occurring deletions in the human Y chromosome"
by Lange et al., Nucleic Acids Research, 2007, pp. 1-7.
