this happens all the time in other animals. i'd adopted two cats (boy and girl) who were littermates but had different fathers. their coat patterning and eye color were different even though their coloring and (small) size were similar.

- cimmanom 8y agoAnimals 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).
