Well, going back to donkeys and horses, they are genetically compatible due to similar enough genes, so if we were to draw a real world comparison aside from that, we'd be pretty hard-pressed. Think of it like how Superman can have kids, even though he's not anywhere close to being human in terms of genetic code. It works because the setting says it does, and unless Monty gets into the nitty gritty, we might never get a definite answer.

How were the faunus even made? Like... are they technically mules in a sense?
