Dany is a Targaryen, Jon is half-Targaryen. The Targaryens are famous for losing their minds due to their compound inbreeding. If Jon and Dany were to have any offspring, there is a strong possibility that they will succumb to the Targaryen madness just like their grandfather/great-grandfather, the Mad King. Hopefully, Jon will be the Targaryen madness since he's half-Stark. As for Dany, a lot of her actions suggest the apple hasn't fallen that far from the tree.
