Sabino 1
Summary
Horses that have inherited one copy of the version of the KIT gene known as sabino 1 generally have high socks to above the knees and hocks, belly splashes and large white markings on the face. They can also have roaning and or spotting extending up their mid-section.
Genetic testing for sabino 1 can tell you if your horse has this well-known gene. When sabino 1 is inherited in combination with another white marking gene (e.g. frame overo, tobiano, appaloosa or a second copy of sabino 1) the foal will be at least 90% white. These foals are frequently completely white.
It is usually a good idea to test for the related W20 and W34 genes too.
