Subject: Re: [DNA] Help Interpreting Results for D9S919
Date: Sat, 14 Mar 2009 08:30:23 -0700
The paper you need to examine is here:
I think that unless you have the 9 or 10 allele that it is difficult to
conclude anything concretely regarding Native of the America's ancestry
from D9S919 (D9S1120). This was my conclusion anyway after reviewing
the above paper ...
