This panel is recommended to persons who tested I1-Z140+ before or who have a clear prediction for this haplogroup.
With this DNA test we start with 4 key SNPs

A196
F2642
S1953
S1990

and 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.



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.
