Realistic Horse Genetics Mod (1.20.1, 1.19.4) adds biologically accurate genetics for Minecraft horses. Horses can be dun, palomino, bay, black, buckskin, chestnut, gray, roan, white, pinto, leopard spotted, and many other colors. If this is all new to you, don’t worry, just breed the colors that you like and there’s a good chance you’ll get more of them. You may even get an unexpected color from recessive genes. The color genes include extension, agouti, dun, cream and pearl, gray, silver dapple, tobiano, roan, frame overo, splashed white, sabino and dominant white, leopard complex, mushroom, champagne, and tiger eye. These genes are testable in real life and likewise they can be tested in game by using a book on a horse. There are also hidden genes, not testable, controlling traits with genetics that are not known in real life. Flaxen, seal brown, sooty, rabicano, shade variation, and how quickly or slowly a gray horse changes color are all affected by these hidden genes.

In vanilla Minecraft, it is sometimes easier to just find a good horse than to breed one. With genes controlling the stats, there is actually a reason to breed. Horses will typically spawn with stats that are pretty close to average. However, foals are just as likely to be better than their parents as they are to be worse. This is an important difference from the vanilla system, where once the parents are very good their foals are almost always worse than them. That means once you have good horses, it is easier to breed very good horses with genes than with the vanilla system. In exchange, you need to be careful – there are some pairs of horses that will always produce foals that are exactly as good as them, never better nor worse. This happens if horses are too inbred. You can avoid inbreeding by keeping a larger population of horses, or if your horses are already too inbred you can reduce it by breeding them to an unrelated horse.

Horses can have a wide range of sizes. Most that spawn will be 12-15 hands high, but you can breed to get miniature horses, draft horses, or any size in between. Smaller horses can fit in smaller spaces (sometimes even on boats!) while larger horses have more health and can carry heavier riders. Tip for breeding very large or small horses: Try to avoid inbreeding and keep genetic variation high. Even a horse that is not your very largest/smallest may have some of the genes you want.


  • Genes control color, speed, health, jump height, and size, as described above.
  • Non-mendelian genetics including chromosome linkage where applicable.
  • Put a carpet in the horse armor slot to use it as a decorative saddle cloth.
  • Genetic testing, right click on a horse with a book.
  • Like the mutations in vanilla Minecraft, there is a small chance an allele may be chosen randomly instead of inherited from the parents (by default 1/10,000 per allele).
  • Peaceful creatures and villagers can also ride the horses. Mount/dismount them using Ctrl + right click. (new in version 1.5.0) – Starting with Minecraft 1.17, this feature was moved to a separate mod, Ride Along.
  • Horses spawned in village pens have a small chance to start off tamed and saddled.
  • Netherite horse armor.
  • Highly configurable.
  • Genders, including pregnancy. Stallions can be bred much more often than mares. Gender is visible from the horse’s inventory screen.
  • All horses are trained to ground tie and will stay still while saddled.
  • Foals can grow gradually into their adult size and shape.
  • Change how long foals take to grow up.
