If the gods don't have DNA (which is the explanation as to why its not gross for demigods to date each other despite being related) how come their kids resemble them and inherhit their physical traits? Now I don't know much about biology so sorry if I'm being dumb. This question has plagued me since the first series came out
The same way Apollo can have kids with a guy, the same way Athena’s kids are born from her head. The same way Sally meet Poseidon for just one summer and Percy was born in summer. The same way Zeus and Hera are siblings.
You can blame it on the fact they are gods and nature rules don’t apply to them the same way it does to humans.
