I noticed she said that Sims 2 was more realistic with black and brown hair being dominant and blonde and red being resesive, but that is not how it works in real life. I'm glad they moved away from that idea for Sims 3 and 4 and hope they never go back to it.
What I was meaning here is that in Sims 2 if one parent had brown hair and the other had blonde, the child always had brown hair when in real life they have equal chance of having either brown or blonde, which is how it's done in Sims 3 and 4.
No, that's not true for Sims 2. If both parents were made in CAS, then yes, because they were both homozygous, meaning their dominant and recessive genes were the same, e.g brown or blonde. But a child of that couple may carry on a blonde gene as recessive and that gene may become visible in future generations.
Edit: I'm not really good at explaining biology, especially in English, but here's a good set of articles about how genetics in Sims 2 works: https://thesims2.livejournal.com/5219452.html
