All R1a please join! Our focus is to understand the R1a haplogroup and explore the deeper structure of R1a1a (M198) and all its branches, subclades and clusters.

Join to be further advised by our broad team of administrators, or to contribute to further understanding of the R1a subclades.

Members are often encouraged to test 67 STR-markers or more, and/or SNPs according to their haplotypes, to discover which subclade of R1a they belong to. Please ask our expert advice before ordering any SNP tests. We can then give appropriate recommendations in private email.
