Reply to comment by ClarkFable in Mitochondrial DNA Is Working Its Way Into the Human Genome by molrose96

Mitochondria have their own chromosomes, tens to thousands of copies per cell. Your mother's egg cell had its own mitochondria with its own DNA. That's what all your mitochondria have now. Somehow, the mitochondria from sperm are specifically targeted and eliminated. We're still working on that mechanism.

Sperm don't have mitochondria in the first place, do they not?
