Hope this helps Dennis Wright ****************************************************************** Hi, I am entering some values into Y-search from Genebase for my Proctor DNA Project and was wondering if there are any conversions necessary to compare them to FTDNA. Also, I cannot find the spot to enter STR 439/GATA A4. Can anyone help me out? Thanks, CeCe Moore www.yourgeneticgenealogist.com www.studiointv.com
