Thank you Dean.

Hopefully others (and some experts) will still share
their thoughts.

Do we need our entire personal Y-chromosome sequenced?
I would think we just need SNP tests of those areas
which will identify our sub clad. Knowing our sub
clad and a "sufficient" number of STR markers should
allow us to only have close matches with close
relatives. I wonder how many markers is sufficient?

Sincerely, Peter

Thanks for posting it. I really enjoyed that article.

Yes, genealogists will probably always have to be
content with the
crumbs left from other market driven development. I
didn't take Peter's
message to suggest reconstructing entire pedigrees but
rather male line
descendancies. If the entire personal Y-chromosome
can be sequenced
then it may indeed be possible to identify individual
paternal ancestors
by SNPs given enough tested descendants.
