Good point, because things acquired like diseases can be inherited. But then we are then going to have to guess if it's spreadable or not. I assume that the Dark One powers aren't spreadable unless it separates from the host (which I doubt). Plus, you need great magic to actually put darkness into a baby.

All babies are blank vessels by nature, so by nature, the baby should be totally normal. Now, why I say male versus female Dark One is because the baby would have to love within the Dark One for an extended period of time. Also, depedning on immortality, it could be possible that female Dark Ones simply can't have children (because they don't age).

So, I guess we could try to argue just the chance at having magic (not DO magic or immortality). Thus, I would say that magic in Once is iffy. Emma has magic, but neither of her parents do. Yet, they had a second child and he's apparently normal. Cora has two kids and one was a natural prodigy, while Cora and Regina have similar if not the same color smoke and both had to learn it. Then we have Emma who is magical to the core, but Henry was born normal.
