Genetics

@DivinylsFan The setting in nraas' SP about facial blending only shifts features a very small amount. I doubt the human eye could detect it and the only way to be sure is to compare slider numbers in CAS. It's not actually "blending" of parental features, rather than an occasional small shift in slider position. From memory, it does increase the chance of hair and eye colour being inherited from a grandparent but not facial features. There is a genetics mod (not Nraas) that does blend parent features but, as far as I could tell after playing several generations, it only blends the genetics of the parents and the grandparents' genetics don't factor into the blending. Without mods you would only get inherited whole features from either parent and there would be no generation skipping, only the passing of whatever feature/s were passed down to the parent. The genetics are basic and dominant and recessive genetics are non-existent.
