Snowflake Appaloosa (also known as "Flecks") are a type of Appaloosa horse with white spots, flecks, or splotches which are distributed in random patterns all over the body. The Appaloosa's spots are the result of a combination of genetics, white hair, and skin pigment that causes white hair to develop in certain areas.
This pattern is different from the traditional leopard pattern which is found in regular Appaloosa horses. It usually appears when an individual has one or more white parents and then inherits genes that produce this variation. It is thought that these flecks may be caused by a mutation or by an intensification in the pigment gene with age.
