This is a 2 round panel that pinpoints the terminal SNP in haplogroup A00, A0, A1a or A1b1. This panel is suggested when 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:
L419
Y23660

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.

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



YSEQ won't test all displayed SNPs and reserves the right to replace not working SNPs against phylo-equivalent alternatives if necessary.
