Better genetics is a 26.2 datapack that adds a twist to animal breeding. Wild animals now spawn with random statistics. Your goal is to find animals with good properties and breed them together.
BASICS
Craft an Animal Analyzer with a wheat and a carrot on a stick, as shown bellow.
Right click an animal with the Animal Analyzer to view its statistics. Hover over lines of text in chat for additional info about a certain statistic.
Note 1: Right-clicking some animals (horses, wolves, llamas etc.) may not trigger the scan. To get around that either punch them or try standing furether away (approximately 7 blocks away works best).
Note 2: Punching an animal with the Animal Analyzer or a mutation catalyst (see below) deals no damage.
FEATURES
Animal breeding is the main focus of this datapack. Offspring inherit stats from their parents: the baby's stat value is the average of both parents with a small chance for it to be increased by one. If the Easy Breeding setting is turned off, the stats may also be lowered by one. You can get perfect animals by selecting babies with stats better than their parents and breed them together.
MUTATION CATALYSTS
Mutation catalysts are special items that allow you to increase most stats of an animal without breeding. They come in two varieties:
They do not work on bees for technical reasons.
COMPATIBILITY
Depending on the feedback I may update the datapack to support more animals, add more features to already supported mobs or balance them (because all animals are balanced but some animals are more balanced than others). Therefore any feedback and suggestions are highly apreaciated.

FEATURES
- Most animals get asigned a Growth stat (determines how fast babies grow into adults) and a Fertility stat (determines how often they can breed).
- Most animals have the ability to get asigned a Special Mutation.
- Cows, pigs, sheep, chickens, rabbits, horses and llamas now drop different amounts of meat, leather, feathers etc. depending on their stats.
- Chickens may lay eggs more often depending on their Egg Laying value.
- Sheep have a chance of spawning with the ability to regrow wool without having to eat grass.
- Some rabbits are more likely to drop rabbit's foot.
- Bees can produce honey faster depending on their stats.
- Wolves now spawn with randomly generated Attack damage, Armor and Movement speed attributes.
- Cats will bring players different morning gifts based on their Personality. Some cats will also give their owners positive potion effects.
- Some parrots will apply negative potion effects to hostile mobs.
- Foxes have many boosts that help accelerate the breeding process of nearby animals.
- Striders and camels will spawn with varied speed.
- Goats have varying ramming damage and aggression.

MUTATION CATALYSTS
Mutation catalysts are special items that allow you to increase most stats of an animal without breeding. They come in two varieties:
- Weak catalyst (common): increases one non-max stat by 1
- Potent catalyst (rare): increases all stats that can be increased by 1.
They do not work on bees for technical reasons.
COMPATIBILITY
- Version: Minecraft Java 26.2 or higher
- Servers: This datapack is compatible with any 26.2 vanilla server. I cannot guarantee it will work on Spigot and other modded servers.
- Other datapacks: Better Genetics will conflict with any datapack that changes animal loot tables, such as datapacks that make animals drop their heads. It should work in combination with most other datapacks.
Depending on the feedback I may update the datapack to support more animals, add more features to already supported mobs or balance them (because all animals are balanced but some animals are more balanced than others). Therefore any feedback and suggestions are highly apreaciated.

Have something to say?
I am having an issue with sheep, when I shear a coloured sheep it always drops white wool. Is there some specific configuration I am missing?
I was looking through the sheep colour json files (eg. \data\minecraft\loot_table\shearing\sheep\black.json) and I see this value set to white:
"random_sequence": "minecraft:shearing/sheep/white"
Try updating the pack on a backup of your world and see if everything works.
Edit: I managed to used visual code Studio to edit the code so that it would work for me but I am not good at coding so it do be a bit funky
"241", "226", and some others, depending on the animal.
Any way to solve?
