Sabino (SB1)
Sabino is an incompletely dominant white spotting pattern that can appear on all three base coat colors, this means horses with one or two copies can have different appearances, a horse with homozygous Sabino (SB1/SB1) will appear almost completely white.
Sabino horses typically have irregular white markings with jagged or roaned edges, often including high white socks, facial markings, and scattered white hairs throughout their coat. This can sometimes be confused with the Roan gene if the marking is extensive.
How Sabino Works In-Game
The appearance of Sabino depends on whether the horse has one or two copies of the gene.
Horses with one copy typically display irregular white markings, while horses with two copies have much more extensive white spotting that can cover almost their entire body and impact their mane/tail color.
This means that horses with two copies may appear almost completely white, making it difficult to distinguish their original base coat color.
Sabino can vary significantly in game, some overlays are minor and only cause leg and facial markings, whereas some are more extensive and can appear like roaning across the horses coat.
Sabino Inheritance
Because Sabino is incompletely dominant, one copy is enough for the pattern to visually show, but two copies produce a much more extensive white pattern.
- SB1/SB1 - The horse has two copies of Sabino 1, typically displays an almost entirely white coat, and will always pass Sabino to its offspring.
- SB1/n - The horse has one copy of Sabino 1 and will have a 50% chance of passing Sabino to its offspring.
- n/n - The horse does not have the Sabino 1 gene and will not visually display it or be able to pass it to its offspring.
Genetic Testing
Sabino is a genetically identified white spotting pattern.
In our genetics system, Sabino is a testable white marking. Players can have their horses genetically tested at a veterinary office to determine whether they carry one or two copies of Sabino.
