The reason is that Y chromosome exists only in males, and is passed from
father to son.

Once the "mutation" is introduced, it is copied to all following
generations.

The group R has accumulated seven mutations
known as M9, 92R7, M45, M74, P27, M207, M306

The group J does not have all this mutations. To turn from R to J, one needs
to undo all these seven mutations !
