Ah...I misunderstood your comment and I misunderstood how it works. I thought human sperm had no mitochondria. Turns out that is dramatically not the case, but the sperm's mitochondria is killed off by the egg, and that's exactly what you said. I had thought you were saying the sperm had mitochondria and the egg killed THE EGGs mitochondria off. My mistake.
