Every time an Occult and Human have A Baby

I usually have more non-occult kids and I play vanilla. I even did a test with vampires on a dark ley line and still got only a few, though it has been a while. (By the way, I think it would be really cool to have lot traits for the other occults like that. Maybe even one to encourage alien abduction where it was nerfed into the ground.)

Anyway, I don't see any real reason one trait would necessarily be more dominant than the other. Since they are fictional anyway, it is whatever fantasy your brain wants for them to be dominant or recessive genes. Sims 4 seemed to pick equally heritable.
