This is a 2 round panel that pinpoints the terminal SNP below N1a-Z1936 (formerly N1c). This panel is suggested when you have tested Z1936+ or if you have a clear prediction for this haplogroup according to your Y-STR results.

In the first round 2 important SNPs will be tested to find out the main category:
VL62
CTS4329

In the second round 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.
