## EquestriCraft Color Genetics Guide
EquestriCraft's genetics system is based heavily on real horse coat color genetics, with a few simplifications made for our audience. Most colors, dilutions, patterns, and breeding outcomes follow real world inheritance, while some areas have been simplified to provide more variety and easier gameplay.
When breeding, foals inherit genes from both parents. Some genes are dominant and only require one copy to be visible, while others are recessive and require two copies. This guide explains how colors are created, how they pass to foals, and what combinations are possible within EquestriCraft.
