Re: a couple more questions
Men DO have this mitochondrial DNA, right, they just don't pass it on, right?
​
As I understand it that's right. Sperm only contributes to the nuclear DNA of a fertilised egg cell - the mitochondrial DNA is already in the mitochondria of the egg cell.
​
I just Googled and it seems in mammals at least that sperm does contain mitochondria (and so mitochondrial DNA) but they are destoyed by the egg after fertilisation.
