This is the world's largest and most complete haplogroup J1 panel.

In the first round 3 important SNPs will be tested to find out the main category:
L858
FGC1707
FGC5

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. YSEQ is reserving the right to replace SNPs by phylo-equivalent substitutes.

See this tree diagram to understand the processing of this panel:



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