Mod Collection: Genetics Overhaul!

This is a collection of mods that completely change the game's genetics.

Main Mod

Makes genetic inheritance from grandparents possible (TS4 doesn’t support this, in case you didn’t know)

Remembers natural hair and eye colors, so your Sims can dye their hair and wear colored contact lenses without affecting their genetics

Fixes the inheritance of occult eyes (children usually inherit random ones)

Occult mutations

Customize probabilities so that genetics work the way you want it to!

Better Inheritance

This mod enforces stricter inheritance rules.

The exact skin tone is inherited, not just an approximate one of the same category (cool / warm / neutral)

Parents’ skin colors do not blend: either one or the other is inherited

Archetype (race) is taken into account when inheriting skin, hair, and eye to minimize weird combinations like dark-skinned Asians with white hair

No Weird Age Up and Random Genetics

TLDR; this mod fixes the ugliness :D

No more small chins

Fixes the odd placement of facial features, especially the eyes and mouth

For many sliders, randomness is limited or completely disabled

Affects both NPC generation and aging

All modules from this collection are independent and don't conflict with each other!

They are also compatible with most of the mods, including:

MCCC by Deaderpool

Relationship & Pregnancy Overhaul by Lumpinou

Realistic Childbirth by Pandasama

NPC Family Genetics Fix by deadlystringnyc

Wonderful / Wicked Whims by TURBODRIVER
