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).

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.
