So if Naruto and lets say Hinato for example were to have a child, would that child possess the byakugan. I mean as far as I know, all characters with sharingan or byakugan have parents who are both from the same clan.
This is one reason why I don't think Naruto and Hinata will end up together. I mean it would just be weird, Kishi would have to troll us for it to make sense.
