Yes. There are very few SNPs appearing in more than one location in
the haplotree (i.e., indicating the mutation happened more than once),
but you would expect the vast of majority of SNPs to be positive only
for the clade they define.

If the patrilineal line you are studying is R-1b1a-2a1a-1b4, then this
individual is positive (or would be if tested) for all SNPs upstream
of and including L21:

Thank you, Diana. I appreciate your info especially the link.
