The Sims 4 has less advanced genetics than previous Sims games?

The sims 2 also had very limited trait options from what I’ve seen (never played unfortunately) so it was probably easier for them to put a genetics system into place - would be cool to see one with all the traits of the sims. Would be fun with freckles, eye color, hair color, etc to turn up generations later. I end up editing these traits in
