Z63 represents a large group downstream I1-M253 which is mainly observed in central Europe. We recommend this DNA test if you are already tested Z63+ or if your STR markers closely match with an I1-Z63 group. With this DNA test we start with 4 key SNPs

BY351
S2077
Y2245.2
L1237

and then we work down the branches iteratively until we have found your position on the given tree.



The test is completed when the unique phylogenetic position on the tree has been determined.
