Minecraft Mods Wiki


Genetic Animals is a mod for 1.16.4+ Minecraft Forge that is still in beta. Genetic Animals is a realism mod that replaces cows, pigs, chickens, sheep, llamas, rabbits, and mooshrooms with a more dynamic genetically driven entity. All animals included in the mod have their own unique genes that can be inherited by offspring allowing the player to selectively breed for colors, size, shape, and loot. Animals also have several other realism changes such as grazing and eating food, a hunger mechanic, sleeping, a healing mechanic, genders, pregnancy and/or egg fertility. If using creative mode or commands, you can use Genetic Animals spawn eggs to summon the mod animals.

Getting Started

To get started with genetic animals you will need to find an adult male and female (or just any 2 if omnigender is enabled in the config) animal of the same species and breed them using their breeding food item. If the animal is a mammal they will fall pregnant rather than instantly spawning a baby, if they are a chicken they will lay a fertilized egg which can be thrown to hatch it. Once the animal is born it will grow slowly over time rather than instantly, this can be sped up by feeding them their breeding item.

Villages will have a few pure breeds per village, explore the world to find more breeds. Animals found in the wild will tend to have traits adapted for their environment or traits that are just endemic to the biome. In an upcoming release animals found in the wild will be much likely to be fearful of or aggressive to players, while village animals will remain docile. The Wandering Trader will also start selling more docile and unique animals.

Find animals you like in villages and in the wild and keep the best ones for breeding the next generation, if you use your favorites for breeding they will produce offspring that share their traits and occasionally you will get new animals born that have your favorite traits from multiple ancestors.

Unlike vanilla animals Genetic Animals Graze for food, have pregnancies, and slowly change shape and size as they grow. Each animal still has the same breeding items but can also eat a myriad of suitable foods to fill their hunger bar. Genetic Animals will also sleep at night and they will seek shelter from the rain and midday sun. While sleeping or resting Genetic Animals will lose hunger more slowly while restoring their health. Genetic Animals all have their own GUI where you can crouch + right click to view their name, age, parent names (if parents were named before breeding), gender, hunger, health and pregnancy status, taming level will also be displayed in an upcoming version.



Cows breed with wheat and hay bales, but they will also happily eat melon, pumpkin, grasses, vines, oak leaves, carrots, apples, sugar, wheat, and hay. They have one calf at a time and make up to five buckets of milk after birth. Cows have an incalculable number of heritable horn variations, some are quite interesting. Cows can be used for riding and as a pack animal.

Sheep breed with wheat, but will also eat grass, tall grass, melon, pumpkin, vine, hay bale, carrot, rose bush, dandelion, apple, sugar. Sheep give birth to 1 - 4 lambs at a time and make up to one bucket of milk per day after birth. Some sheep are hair sheep which do not make wool but instead drop leather, while other sheep are wool sheep. Some wool sheep will make almost no wool while others will make 3 blocks of wool per day. Sheep are more visibly fluffy the woolier they are and the bigger it is; the more the fleece jiggles.



Pigs breed with carrots, beetroot, or potato. When bred they have 1 to 15 piglets. Pigs are a neutral mob that will attack back if provoked. They can be equipped with saddles and chests but can not be equipped with bridles to steer them with so must be directed with a carrot on a stick. Pigs take 2.5 days to grow from a newborn piglet to an adult but will continue growing for five days.



Chickens use any sort of seed to trigger breeding. Once bred (only female if omnigenders is set to false) chickens lay fertile eggs for a few days that may be hatched by throwing. Throwing eggs to hatch chickens will eventually be replaced by needing the eggs to be incubated by the player or a chicken. Chickens will eat any seeds, sweet berries, dandelions, melon slices, tall grass, grass, bread, eggs, and spider eyes.



Rabbits breed using a carrot or dandelion. A litter of rabbits can be anywhere from just one to as many as thirteen. Rabbits can be fed grass, tall grass, carrots, sweet berries, dandelions, and rose bushes. Some rabbits can grow a fleece and will appear much more fluffy than most rabbits. A rabbit with an enormous fleece will drop one white wool each time its sheared. The more fluffy the rabbit the more likely you are to get wool.



Llamas must be tamed and fed a hay bale each to trigger breeding. Llamas will only have one cria at a time, their pregnancies last two minecraft days and the cria takes five days to mature. Llamas can be used as a pack animal but can also be used for riding. Some llamas will be fluffier and can be sheared for wool, it can take a few days for a llama to grow back their wool once sheared but they will have an interesting haircut while they grow their fleece. In addition to their breeding items llamas can be fed grass, tall grass, carrots, wheat, apples, or sugar as a treat.

Realism Changes

Several other realism changes have been added in addition to genetics:

  • Grazing: cows, sheep, chickens, llamas and pigs will graze when hungry if grass blocks are available.
  • Eating Food: animals eat a wider variety of foods.
  • Hunger: animals need to be fed to be able to breed, produce resources, and grow.
  • Sleeping: animals sleep during the night.
  • Healing: well fed animals will heal while they sleep.
  • Pregnancy: birth is no longer instant.
  • Egg Fertility: chickens must be bred recently otherwise eggs will never hatch when thrown.
