This is a 2 round panel that pinpoints the terminal SNP below N1a-VL29 (formerly N1c). This panel is suggested when you have tested CTS2929/VL29+ or if you have a clear prediction for this haplogroup according to your Y-STR results.

In the first round 3 important SNPs will be tested to find out the main category:
Y5004
L550
M2783

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.
