Animals that commonly produce liters of multiple offspring typically do so by releasing multiple eggs simultaneously in each period of fertility. This also happens in humans in the case of fraternal twins (two eggs each fertilized by a different sperm).
That’s very different from one egg being fertilized by a single sperm and then splitting (which produces identical twins) or being fertilized by two sperm (which is what happened in this case).
- clairity 8y agoright, that was a bad example (multiple eggs with multiple sperm from different fathers, not single egg with multiple sperm). i can't remember where, but i do remember reading about this happening in other animals.
