That may be true for mom, but conservatively, there's between a 1-in-100 and 1-in-20 odds of inheriting none of your father's dominoes.

It's been a while since I've taken high school biology, but the odds should be the same as the mother. Scottish-ness is not something that's limited to the X or Y chromosome.

Mitochondrial DNA will only come from your mother, but I don't think we're talking about that here.

What's the mechanism at play here? Each chromosome pair is one from the father and one from the mother.
