The really interesting question for me is whether the Dwarven resistance to magic and inability to perform it is genetic or environmental, something that I don't think has been definitively settled yet. It seems clear that dwarves and humans descend from a common ancestor that's evolved in different directions. Dwarves have evolved to be shorter and stockier than their human cousins, but did they also evolve their lyrium resistance? Or is it caused by environmental exposure?
If the former, don't expect to see dwarf mages any time soon. If the latter, a few generations born on the surface and there may be dwarves in contact with the Fade and performing magic all over the place.
I don't think so, being the Dwarven one of the most ancient races and once time the most powerful, they should y know if the one who lose the "stone sense" could become mages, even on all those centuries would be one or two mages dwarven (after all thanks to the darkspawn being underground isn't a healthy option )
I'm not sure, but any dwarven who get a open wound and expose to Lyrium get sicked too (at least, that is the case of the merchant at orzammar) so, they are robust against lyrium even can feel it but only have a extra protection against that... so, the most close answer to your question it's : genetic, though on this game i don't like use genetic/science concept for explain things... there the blood it's more powerful than brains and with that is the answer to all the secrets
