Eye color for fictional characters

[halavana]

Found this really cool website that shows how children's eye colors are determined. I've been writing this story in which a family has one green eyed child about every generation and was wondering if that was possible. Well, thanks to the Eye Color Calculator

I found out that, yes, it is possible. Pretty cool.
