This mod is a gene-saver!

If you want your sims to genetically inherit moles or freckles from their parent(s) then download this:

Freckles and Moles genetics

I used to get irritated because my sims with freckles(even a married couple with freckles) wouldn't pass them down to their offspring! With this mod, it's actually possible! The toddler in my avi was born to a mother with a sprinkling of freckles on her nose and a father without them. She has her mother's freckles!

I had that in a while, but almost every single new game-created Sim had freckles or moles. It was a bit much I figure I'll stuff it in temporarily when any of my Sims are actually expecting, then pull it back out between.
