This Project is open for all R1a (R-M512) Y-haplogroup members. We encourage our members to test at least 37 STR-markers in order to review your haplotype.

The chart below is a simple, basic version of the actual SNP tree depicting clade positions and relations as well as approximate dates and probable ethnic or geographical spread. The chart and maps include some estimation and conjecture, and should not be taken as proven fact. Most R1a1a clades and branches cannot be fully characterized by simple ethnic labels.


Please ask our expert advice before ordering any SNP tests, including the "SNP Pack" test. We can then give appropriate recommendations in private email.
