Animal Genetics
by Vexxen1
Animal Genetics lets players breed animals by inheriting traits from both parents, so a faster horse or pig can be selected over generations.
What it does
Pigs, sheep, cows, horses, striders, foxes and wolves carry genetic data that is passed from two parents to their offspring. Each newborn receives a mix of its parents' genes, and the player can keep breeding the animals that show a chosen trait until a line reaches the desired result. The genetic math is simple to follow while the effects of genes on one another are more involved.
The genome is stored as a number built from 31 binary digits generated when a world starts, and the number is kept on a scoreboard. Each part of it controls a visible or gameplay effect. Some genes change appearance, such as coat darkness or spots on a horse, while others change speed, and the effects of genes can counter or reinforce each other. Combined information from both the female and male parent is used when the offspring is created.
The mod runs on the server, so the server needs it installed. Players may add it on the client for extra features but do not need to. It is published for Fabric, Forge, NeoForge and Quilt, and its builds cover 1.19.2 – 1.20.2. The code is released under the MIT License and is not open source. A data pack version is also available.
Key features
Selective breeding
Players choose which trait to favor and breed only the offspring that show it, repeating the process across generations.
Inherited genes
Each baby receives genetic data from both parents, and the genes are mixed according to a set of rules.
Trait effects
Genes control visible features such as darkness and spots, and others change values like speed by fixed amounts.
Binary genome
A 31-digit binary genome generated at world start is stored on a scoreboard and read to apply each effect.
