This huge panel covers everything below R1b-U152.
With this DNA test we start with 5 key SNPs:

L2
Z68
Z367
Z56
Z192

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.

See this tree diagram to understand the groupings in this panel:



YSEQ reserves the right to replace not working SNPs against phylo-equivalent alternatives if necessary.
