The R-M222 and Subclades project is open to all individuals who have a derived (i.e., positive) test result on the SNP (single nucleotide polymorphism) called M222 or for any of the numerous known SNPs that lie downstream from M222. Also welcome are individuals without SNP results whose haplotypes conform to the R-M222 and Subclades modal haplotype. If in doubt, please contact a project administrator.
