Group Description

R1b is a branch of the human family tree of paternal lineages. It is marked by a mutation of the Y chromosome named M343.
P25 and M269 are part of R1b along with several large young subclades; L21, U152, DF27, P312, U106 & Z2103. This forum supports the FTDNA R1b project. Please join if you are R1b of any type including predicted R-M269, R-P25.

R1b is the largest haplogroup of men from Europe. Please consider deeper SNP testing. It is strongly recommended to get at least 67 STRs. This helps your right subgroups and filters out false matches. 111 STRs is the new standard for analysis. SNP testing is vital with NGS tests, like Big Y, being the best. Big Y, SNP Pack, FGC, YSEQ and FTDNA Upgrades/Adv Tests are recommended.

Explanations for key why and what Y DNA testing questions are at

When you receive SNP results, please stay n the R1b project, but consider major subclade projects:
R1b-P312/S116 (inc. DF19, DF99, L238)
R1b-M343 Basal (P312- U106- people)

Non-Y DNA questions are best for the newbies group http://groups.yahoo.com/groups/DNA-NEWBIE/

The group's goal is to advance deeper testing and understanding of R1b. The group is for those in the project and interested in project goals. Do not post non-R1b topics or very general topics, specific agendas not aligned with the project goals, intentional commercial promotion, nor denigrate people, their testing decisions, companies or products, or otherwise be inflammatory. Do not use this forum for vendor competitive selling and analysis. This often leads to negative selling and discouragement. This can result in a ban without notice.
