The question is, does being a product of True Love pass down genetically?

Personally, I don't think so. To me, it's a unique and possibly rare situation. It might also require extraordinary True Love, like what we see with Snow White and Charming.

And I definitely don't think the Dark One's magical ability would pass down -- it's not organic to Rumple, it's given him through his curse.
