Inheritable Coat Color
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Abstract
Inheritable Coat Color is a Minecraft mod that introduces a realistic genetic inheritance system for sheep coat colors and wool characteristics. Built as an example implementation of the Chromosome Lib framework, this mod replaces Minecraft's simple color inheritance mechanics with a sophisticated genetics-based system inspired by real-world Mendelian inheritance.
Key Features
- Genetic Inheritance System: Sheep offspring inherit coat colors through a multi-gene system featuring dominant, recessive, incomplete dominant, and sex-linked alleles.
- Complex Color Genetics: Coat colors are determined by multiple interacting genes including:
- Melanin enzyme production (black pigment).
- Uranidin enzyme production (yellow pigment, X-linked).
- Melanin metabolic enzyme (affects pigment attachment).
- Dilution genes (incomplete dominance affecting color intensity).
- Pink mutation gene.
- Special pigment genes (magenta and green, with co-dominance).
- Hair Length Trait: Introduces long-haired and short-haired variants through a single gene with Mendelian inheritance. Long-haired sheep produce more wool when sheared.
- Chromosomal Mechanics: Genes are mapped to specific chromosomes with realistic mutation rates and crossing-over probabilities.
- Sex Determination: Implements XY sex determination system with sex-linked traits.
