This panel is suggested when you have tested M172+ or if you have a clear prediction for this haplogroup according to your Y-STR results.

In the first round 5 important SNPs will be tested to find out the main category:
L26
L24
PF5197
Z2227
M12

and then we work down the branches iteratively until we have found your position on the given tree.
This panel includes the following downstream panels in the price:
J2a-M67 Panel
J2a-L24 Panel
J2a-PF5197 Panel
J2b-M12 Panel
