# 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.
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 to major R1b projects including this one.
Eligible R1b haplogroups that are presumed U106- and P312- based on phylogenetics.
