I'm setting a story in a sorta-fantasy sorta-real world, and I'd like my main character and his sister to be blond, but they've also probably got Japanese heritage somewhere in their family. His father is most likely white. So, I don't know what kind of weird gene mixes that would involve (quarter Japanese, maybe?), or if perhaps I could end up giving the kids some other lightish-colored hair that isn't necessarily blond, but I really would like them to have a light-haired look.
And if anyone has some examples of what a white/Japanese child would look like--photographs or basic description or something, regarding eye colors, facial features, body type, anything--that'd be nice.
As for what the white half of his family's ethnic origins are, I dunno. I'd like to be lazy and say "American!!" so I can pull the "melting pot" card and say his father is a Generic White Guy, if such a thing exists. But his family name is Tulving, and I cannot find out the origin to that (Google fails me again), so if anyone happens to know...
Thank you for your help!
