This panel is suggested when you have tested Z255+ or if you have a clear prediction for this haplogroup according to your Y-STR results.

In the first round 4 important SNPs will be tested to find out the main category:
Z16437
Z16434
Y16467
Y12458


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.
