Kishi has stated multiple times that he sucks when it comes to scientific explanations of things, because he doesn't understand it himself. Put plainly, you're right; strictly speaking its impossible, but in the Naruto universe, very possible. And, actually, if you buy into the anime, people were trying to pass along DNA like that. They tried to recreate the Wood Release, due to its power, with genetic experimentation. My guess is that it wouldn't be as out in the open because of how taboo something like that would be, but that's just my speculation.
