Hello List,
A new Y-DNA project has opened at FamilyTreeDNA, called
"Fathers-Sons-Brothers":
http://www.familytreedna.com/public/Father-Son-Brother/
It's intention is to consolidate all father-son and brother-brother
pairs Y-DNA tested at FTDNA. These pairs are extremely valuable for
estimating the frequency of mutations.
The project has only just opened, today, so the admins are still in
the process of building the web site, but it's not too early to join.
To do so, please click the "Join Projects" link at the upper left on
your member page, then choose "F" under "Surname Projects," then
scroll down and click "Fathers,Sons,Brothers."
I have joined my father and his brother (MATTHIESEN 67/67), plus two
first cousins who are brothers (STRAUB 110/111).
If you are part of such a pair, I encourage you and your other half to
please join the project. All haplogroups are welcome, and you don't
have to have tested the same number of markers.
Diana
