This is a 2 round panel that pinpoints the terminal SNP below Z93. This panel is suggested when you have tested Z93+ or any downstream markers like e.g. Z94+ or Z2124+.

The first round tests 4 important markers and gives you an answer to which major category you belong to:
L657
Z2124
F1345
Z2123

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