Do you remember that your Sim's children could get their grandparents' genes/facial features in The Sims 2 and The Sims 3? (More in The Sims 2 if I remember correctly) I would like to see improvements in The Sims 4's genetics system. For example:
- More hair color tones/ hair colors for children (both in CAS and in the actual game when your Sims have a baby)
- If I play Legacy Challenge, I would love to see that my Sims' children could get their grandparent's or aunt's/uncle's features (Grandma's dark hair, Grandpa's blue eyes, Aunt's nose, etc.)
Thank you SimGurus if you read these suggestions

even though I know you do!

I couldn't agree more! This is a wonderful suggestion! In my opinion, it's the only thing I am not 100% satisfied with in the game.
As a fellow legacy player, I have 7 generations born already and every single generation, it seems they only inherit traits from their parents.
@MsPhy - I checked out your family tree, and to me, it seems like Gen 3 has Gen 2's nose, not Gen. 1's... It doesn't seem big enough to be Gen 1's.

It occurs to me that maybe you're looking for traits that skip generations rather than being passed from generation to generation. If that's the case, of course my relatively small family tree will show you nothing, unless baby Cyrus shows up with something that did not pass to his mother.
