Sims 3 genetics were a mess. I guess that's what you get when on the CAS you can't define people in black, brown, blonde and red. Since there was a spectrum of color the range comprehended between the father and the mother would apply to all their children so they can get any color in that range. It made sense in the sims 3 even tho poping out purple haired childrien out of ginger parents seems a little unlikely
I don't know how they will handle genetics but I hope that going to the hair salon and changing your hair color doesn't change you genetic code as well
