This mod makes hair and eye color genetics more realistic. It also changes the alien eye color genetics.
With this mod:
  • 🟨blond hair is:
    • dominant over 🟧red,
    • still recessive towards 🟫brown and ⬛black.
  • 💚green eyes are:
    • dominant over 🩵light blue and 🩶gray,
    • still recessive towards 🤎brown.
  • 💙dark blue eyes are:
    • in the regular version: as recessive as 🩵light blue and 🩶gray eyes.
    • in the hazel version: as recessive as 💚green eyes,
      • use the hazel version if you use a hazel, amber, or green default replacement for dark blue eyes.
    • in the brown version: as dominant as 🤎brown eyes – as originally,
      • use the brown version if you use a brown or black default replacement for dark blue eyes.
  • 🖤alien eyes are:
    • dominant over all human colors like 💖custom eye colors – originally, it was as dominant as 🤎brown,
    • available for all Sims – originally, only Sims with alien skin tone could have alien eyes,
    • visible in Bodyshop.
Use only one version at a time.
Existing Sims' appearance won't be affected.
Update (24 Jul 2017): Added a new version for those who use brown or black default replacements for dark blue eyes.
Foundation
This mod is based on a simplified real life model of genetics in which there are:
  • two hair color genes: a dark/blond gene and a non-red/red tone gene,
  • two eye color genes: a brown/non-brown gene and a green/blue gene.
In the game, there is one eye color gene and one hair color gene. So this mod is an approximation of an approximation [sic] of real life genetics, which is much more complicated.

If you want to know more about the in-game genetics, check out my description with examples.

Technical comparison
A color with a lower genetic value is dominant over a color with a higher genetic value.
For example, the 🤎brown eye color (genetic value: 1) is dominant over 🩵light blue (genetic value: 2).

Way to resolve
Creature Fixes by PescadoMy mod must load after the conflicting mod.
any other mod that changes genetic values, visibility in the catalog, or townification of blond hair, or alien, green, or dark blue eyesI don't recommend using it with my mod.
Instead of using my mod or the conflicting mod, consider making your own rules with Genetics DIY.
