🪽 White Patterns Tobiano (TO) Tobiano is a dominant white pattern gene that creates smooth, rounded white patches that often cross the topline. Inheritance & Expression Genotype Result TO/TO 25% Expressive Tobiano 75% Medium Tobiano TO/n 50% Medium Tobiano 50% Minimal Tobiano n/n No Tobiano Characteristics Rounded white patches White legs White crossing over the topline Dark head with normal facial markings Splashed White (SW) Splashed White is a dominant white pattern that creates crisp, bottom-up white markings, often giving the appearance that the horse walked through white paint. It commonly produces high white legs, wide facial markings, and blue eyes. Genotype Result SW/SW 25% Expressive Splash 75% Medium Splash SW/n 50% Medium Splash 50% Minimal Splash n/n No Splash Characteristics Crisp-edged white markings High white legs White underside Blue eyes are common Sabino (SB) Sabino is a dominant white pattern that produces irregular white markings with roaned or jagged edges. It commonly causes high white legs, extensive facial markings, belly spots, and scattered white hairs along the body. Genotype Result SB/SB 25% Expressive Sabino 75% Medium Sabino SB/n 50% Medium Sabino 50% Minimal Sabino n/n No Sabino Characteristics Jagged, irregular white markings High uneven white legs Wide blaze or extensive facial white Brown eyes are common Frame Overo (O) Overo is a dominant white pattern that creates irregular, horizontally oriented white patches that rarely cross the topline. It typically leaves the legs dark and is often associated with bold facial markings. Genotype Result O/O Lethal White Syndrome O/n 50% Medium Overo 25% Minimal Overo 25% Extensive Overo n/n No Overo Characteristics Irregular, jagged white patches White rarely crosses the topline Small leg markings are common White is concentrated on the sides and neck Since O/O is lethal, there is no expressive category for homozygous horses because they won't survive. Tovero Tovero is not a separate allele, but rather the result of a horse inheriting both Tobiano and Overo pattern genes. This combination produces a unique blend of characteristics from both patterns, often including large tobiano patches with overo facial markings, blue eyes, or irregular white markings. Characteristics Combination of tobiano and overo traits White crossing the topline Irregular body markings Blue eyes are common White is concentrated on the sides and neck Leopard Complex (LP) Leopard Complex (LP) is a dominant pattern gene responsible for Appaloosa characteristics. On its own, LP may produce only minimal characteristics Inheritance Genotype Result LP/LP Strong Appaloosa Expression LP/n Moderate Appaloosa Expression n/n No Appaloosa PATN Modifiers PATN1 is a dominant pattern modifier that works with the Leopard Complex (LP) gene to increase the amount of white and spotting across the body, producing patterns such as blankets and leopard spotting. PATN2 is a dominant pattern modifier that works with the Leopard Complex (LP) gene to expand Appaloosa white patterning. It typically produces more white expression than PATN1. Example Outcomes LP Status PATN1 Status Possible Result LP/n n/n Minimal Blanket LP/n PATN1/n Leopard and Semi-Leopard LP/LP PATN1/n Fewspot Appaloosa LP/LP PATN1/PATN1 Leopard or Fewspot LP Status PATN2 Status Outcome LP/n n/n Minimal Blanket LP/n PATN2/n Blanket Appaloosa LP/LP PATN2/n Snowcap Appaloosa LP/LP PATN2/PATN2 Leopard or Fewspot KIT White (W20) KIT White, also known as W20 , is a white-enhancing gene that influences the amount of white a horse displays. In EquestriCraft, W20 works alongside facial markings, leg markings, and white pattern genes to determine overall white expression. Unlike Tobiano, Sabino, or Splashed White, W20 does not create a specific pattern on its own. Instead, it increases the amount of white that may be expressed throughout the horse. Inheritance Genotype Expression W20/W20 Extensive White W20/n Medium White n/n Minimal White Expression n/n (Minimal White) Horses without W20 will typically display only small amounts of white. Examples: Star Snip Crescent Coronet bands Pasterns None W20/n (Medium White) Horses carrying one copy of W20 may display moderate white expression. Examples: Blaze Stripe Strip Socks Moderate body white W20/W20 (Extensive White) Horses carrying two copies of W20 may display extensive white markings. Examples: Bald face Large Blaze Stockings Large belly spots Roan (RN) Roan is a dominant pattern gene that mixes white hairs evenly throughout the body while typically leaving the head and lower legs darker. Inheritance Genotype Result RN/RN Heavy Roan RN/n Roan n/n Non-Roan Rabicano (RB) Rabicano is a dominant white pattern that adds scattered white hairs to the flanks and barrel, often accompanied by white hairs at the base of the tail and a distinctive "skunk tail" appearance. Inheritance Genotype Result RB/RB Extensive Rabicano RB/n Medium or Minimal Rabicano n/n No Rabicano Texture Layering Unlike many horse games, EquestriCraft doesn't limit horses to a single coat pattern. Every genetic trait is rendered as its own texture layer, allowing any genetically possible combination of alleles to appear together. This means horses can display combinations such as: Tobiano + Appaloosa Rabicano + Roan Sabino + Splash White + Overo ...and countless more. Because every base coat, modifier, white pattern, hair color, and eye color is layered independently, the number of possible appearances becomes extraordinarily large. With the current genetics system, there are approximately: 1,610,343,593,388,568,719,021,488,209,920,000 (≈ 1.61 decillion unique horse appearances) No two horses are guaranteed to look alike, even if they share the same breed. As new patterns are added over time, this number will continue to grow, making every horse feel truly unique. if a genetic combination can exist, your horse should be able to wear it. Texture layering allows us to create the incredible variety seen in real horses while ensuring every horse in EquestriCraft has the potential to be one of a kind.
