>>24967518Egg Groups don't really say much about biology of a particular species of Pokemon. That being said, if a two-foot tall housecat and a forty-foot long whale can mate to produce viable offspring, it wouldn't be that far of a stretch to think the same could happen with a human.
If the child is almost always the mother's species, what would it matter who (or what) the father is? Pokemon could be like the Asari for all we know.
...maybe that's what happened to all the Indian Elephants?
