# About us

The goal of the R1b Basal Subclades - R1b-M343 (xP312 xU106) Project is to develop the basal branches of the R1b haplotree and investigate the history/distribution of the most upstream (basal) clades of haplogroup R1b-M343.
This is accomplished with the project phylogenetic trees which have resulted in finding numerous undiscovered SNPs, branches and haplogroups recently. The R1b Basal Subclades haplogroup research project is expected to discover new branches and place ancient DNA remains on the Y haplotree.

Eligible members have tested or are presumed negative for SNPs P312 and U106 (P312- U106-) and tested or presumed positive for SNP M343.
If you are predicted R-M269 (red) and have not tested SNPs P312 and U106 please join the R _R1b ALL Subclades project. That project is a gateway into the other major R1b projects including this one.
Eligible R1b haplogroups that are presumed U106- and P312- based on phylogenetics.
