This panel seems designed for McAfee and McDuffee males who are L1065 positive only.
I would not recommend purchasing this particular panel if you don't already know or suspect that your haplogroup is L1065.
L1065 positive males are just one of many different haplogroups represented in the McAfee/McDuffee diaspora.
If you aren't sure what your haplogroup is there are other products available that would be more beneficial than this specific panel.
