Re:Mitochondrial DNA can be inherited from fathers, not just...

Does that not assume that the mitochondrial from both parents are treated equally in terms of inheritance? It seems to me that biological systems do not tend to use random chance most of the times if there is a evolutionary benefit, thus if there is such benefit I would predict that those "tens" would be treated differently from those hundreds of thousands.
If all paternal mitochondria were transferred every time (unlikely‡), then a child's mitochondria would be ~99.99% inherited through the mother.
‡ Unlikely because sperm mitochondria are located toward the flagellum in order to power locomotion, and the capsule at the head is normally the only part which fully penetrates the cell membrane.
