The project includes men with the PF3147 mutation or reliably predicted to be PF3147+. Persons unsure of their G category should join instead the G-Uncategorized Project. The administrator there can help transfer you to the correct G project if your correct category is determined. Many PF3147 men uniquely have two values for the DYS19 marker though many do not. 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 PF3147. Twelve markers are not reliable for this unless you are an exact match at the 12 to an existing project member. The major subgroups of PF3147 are based on men sharing one of the PF3148, PF3270, PF3177, FGC6669, M286, L91, L166 or PF3239 mutations and are included in the PF3147 Project. We also welcome representatives of PF3147 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-PF3147 which will provide better focus to the migration history of our haplogroup G-PF3147 ancestors.
