My redheaded sim dyed her hair blonde shortly after the birth of her first child. Her second child was born with the same shade of hair, despite neither parent having red hair at the time.
I'm wondering then, would grandparents have any influence on genetics? Because my redhead sim had redheaded parents.
I don't think so, by default the game only takes the genes of the parents, thus the redhead baby. Generally, whenever you change your sims hair in CAS/wardrobe or household changes takes place (especially during pregnancy) the baby rerolls its genes. However, in MCC, I believe there's an option where it's possible to include grandparent genetics.
