Hi all,

I know it's not an exact science. However, is there any reason why someone would be predicted as a completely separate haplogroup?

My friend(of Lebanese/Syrian descent) came back as J1 for his Ydna with 23andme.

Running his data through Morley he gets his most likely haplogroup as J2a1i, and least likely as J.

J1 is not even registered. Any reason why this is? Who would be trusted in this case?
