But as the theory with Jon goes, he has very pronounced Stark features. If the Lannister-Targaryen theory holds true, then it would make sense that the Lannister siblings would look more Lannister than Targaryen. Platinum blonde hair and violet eyes are very rare genetic traits, even in the fantasy world of ASOIAF. A child born of two Targaryens would have very high chance of looking unmistakably Targaryen, though one born outside the family would likely show more features of the non-Targaryen parent. There have been many minor characters who claim to have Targaryen blood in their family history, but do not look Targaryen. A combination of generations and dominant traits from non-Targaryen genes would hardly express any visible Targaryen features.

Speaking of genetic traits, it seems that invulnerability to fire is quite selective as well. Dany can survive dragonfire, which I presume to be much hotter than the molten gold that killed Viserys. Jon is not invulnerable to fire, as we see in his fight with the wight where he burned his hand. That may be a point against claims that he is Targaryen. Though even should he turn out to be Targaryen, I don't think he can ride a dragon.

I do wonder if Melisandre and other priests of Rhollar can withstand dragonfire.

Regarding the possibility of marriage between Jon and Dany, I've also read speculation of a union between Dany and Tyrion. Somehow I doubt such a union would come easily as it seems Dany is still only ever attracted to young, physically powerful, alpha-type males. Should they ever be in a relationship, I'd imagine they would need to have a very strong bond of trust established first. Jon would have to consider whether he would be breaking his Night's Watch oath, and Tyrion is still attached to Tysha and married to Sansa at the moment. There's still Jorah Mormant in the picture, where I have no idea what will happen to him, as well as the iron-born racing to claim her as wife, Aegon in Westeros, and I don't doubt Doran Martell still means to join her to the family. May as well nickname Dany the world's most eligible bachelor-ette.
