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

Yes, it is. All the zygote mitochondria are maternally derived an have their own DNA. The fathers are selectively degraded.

Over millennia, genes have been moving from the mitochondria to the nuclear DNA, there are only 13 protein coding genes left in the mitochondrial genome now vs 30,000 ish in the nucleus.
