The project includes men with the F2572 mutation or reliably predicted to be F2572+. If your 37 or 67 or more marker values are different from men already in the project only by 5 or less values, you are reliably within G-F2572. Twelve markers are not reliable for this.. We also welcome representatives of F2572 males who are deceased, unavailable or otherwise unable to join, including females as their representatives and custodians of their Y-DNA. The primary goal of the project is to identify new subgroups of haplogroup G-F2572 which will provide better focus to the migration history of our distant ancestors.
