Also, I'm probably gonna scrap the whole channeling being genetic thing, even I thought it wasn't that great of an idea. As for Magic being primitive, that was really the only way I could think of for it and the One Power to coexist. I'll probably think of a better solution to that problem, unless you have any ideas?
Morgase is a channeler (though a weak one) and Elayne is a channeler.
Aviendha and Rand's child is not only a channeler (or will be according to Aviendha's trip through the pillars) but will be an enormously powerful one, channeling since their earliest memories.
There was mention of some Aes Sedai wondering if by gentling all the male channelers, and by none of them having families, they were in fact weeding the ability to channel from humanity.
As for having them both exist, why having them be related at all? There are a number of powers that aren't related to the One Power, Dreaming, the ability to manipulate plants/trees (though only Ogier presently have that power now), Wolfbrothers. Just have Magic be one of those abilities.
Comparing Magic and the One Power is difficult.
Magic seems to have the advantage in versatility, OP has the advantage in raw power and scale.
