ALL R1b (R-M343), R-M269, R-P25, etc. predicted or tested people should join this project. All P312+, L21+, U152+, U106+, Z18+, DF19+, DF99+, L238+, DF27+, Z2103+, S1194+, V88+ or descendant SNP tested people are welcome. These descendant subclade tested people are critical as role models for new R1b tested folks to compare with. In-depth testers benefit from more people finding them and testing their SNPs. We help identify your subclade and provide guidance. Our gateway service joins you to the correct subclade project. We don't publish your full name or contact info and do respect your privacy. If do not wish to share results or for us to join you to the correct subclade project please do not join this project. For full haplotree click here. Key Steps to Take and Project Operations are on the About/Background page. The Project Goals are to encourage deeper DNA testing to support understanding of the origins of our male lineages, while helping individuals find family paternal lineages and ancestral origins. The project supports full genetic genealogy - the development of the phylogenetic tree starting from family genealogies and breaking through genealogical brick walls to determine the timing and locations of the relationship of families, super-families and clans. The goals include insuring branches are documented on the Haplotree through SNP testing. For help and discussion consider the R1b.YDNA FB group (click here) or go to the project Activity Feed.
