Yes, a SNP is a specific mutation, at a specific spot on the
Y-chromosome. "Mutations per SNP" would be like asking how often does
"Mutations per bp" and "mutations per SNP" are quite different
concepts. One is general, the other specific.

The rate of mutation is given as 1*10 to the negative 9th. So expressing mutation rates as mutations per base pair vs. mutations per SNP would not appear to be different at all. I am missing something?
