Sims give birth to clones - Genetics don't mix

I've seen this happen recently in my game too. I had Lilith Vatore have a baby with Rory from the werewolf pack and their daughter just looks like a clone of Lilith. No resemblance to Rory at all. 

I've noticed it on mine too, only a little differently. The skin color is sometimes that of the father or mother, but the rest is the exact copy of just one parent.

Está um saco de jogar, tantos bugs agora mais esse no meu jogo, todas os bebês que nascem são clones da mãe, as vezes só muda o tom de pele. Extremamente irritante, não arrumam o jogo e sai lançando pacote atrás de pacote, quebrando cada vez mais e tornando nossa experiência horrível. 

They used to mix fine IMO but now it's just EXACT clones and re-rolling/randomizing doesn't do anything except change clothes. I hate it.

Same. I have no CC and mods, but it happens. Please, fix it. It defeats the purpose of the game, cause one of my favorite aspects in the Sims is mixing genetics😢

This!  Also, My legacy family of 11 generations has many twins. Every single time, one twin takes after one parent, and the other twin the other parent.
