This is a 2 round panel that pinpoints the terminal SNP below I2-M423. This panel is suggested when you have tested M423+ 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:

L161.1
FGC7126
CTS10228
S17250

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.

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