Picked Upload! This is a picked upload! It showcases some of the best talent and creativity available on MTS and in the community.
This mod makes hair and eye color genetics more realistic. It's based on a simplified real life model of genetics in which there are two genes of eye color (a brown/non-brown gene and a green/blue gene) and two genes of hair color (a dark/blonde gene and a non-red/red tone gene). In the game, there is one gene for eye color and one for hair color, so the mod is an approximation of an approximation [sic] of real life genetics, which is much more complicated. There are lots of genes that influence eye and hair color, and not every one of them is strictly dominant or strictly recessive.

Update (24 JUL 17): Added a new version for those who use brown or black default replacements of dark blue eyes.

New genetics rules
Blonde hair dominates over red (but still black and brown hair are the most dominant). Dark blue eyes are as recessive as light blue and gray, green eyes dominate over them. Brown eyes are still the most dominant human eyes. Alien eyes dominates over all (like custom eyes) and any sim can use them. They are available in Bodyshop.
Existing sims' appearance won't be affected.
There are also two other versions for people who use nonstandard default replacements of dark blue eyes:
  • simNopke-moreRealisticGenetics-hazel makes dark blue eyes as dominant as green. Use for hazel, amber or green DRs.
  • simNopke-moreRealisticGenetics-brown makes dark blue eyes as dominant as brown. Use for brown or black DRs.
Choose only one version of the mod. simNopke-moreRealisticGenetics is also a version.

Genetic values (greater means more recessive) of the genes:

Rikkulidea wrote how the game genetics works, if you want to know something more about it.

  • Creature fixes by Pescado, because of alien eyes changes. Both mods work fine together as long as my mod loads after Pescado's.
  • Mods changing genetics, visibility in the catalog or "townification" of blonde hair, alien, green or dark blue eyes. I don't recommend using them with this mod. But if you really want to keep those mods, make sure they load after this mod.
