I'm pretty sure that TS2 doesn't actually have a genetic system that works like real life. I think that if you have two parents with brown and green eyes then it'll be a mixture of the two eye colours, and I think it'd be the same thing with the hair colours (I've got a black haired and a brown haired sim who have had 2 children, one with brown and one with black hair). As for the vacation part, yes, children can go on a vacation. Toddlers can't though. I hope this helps! c:
