Colore del matello Tobiano

The Dominant White coat colour pattern in horses can be caused by any in a wide array of related mutations. The resulting pattern can vary anywhere between white markings on the face and legs, up to a completely white coat. Depending on both breed and pattern, variants of the Dominant White phenotype may be referred to as Splashed White, White Spotting, Tobiano or Sabino, among others.

The variant analysed in this test, known as Tobiano, is caused by a dominant mutation to the gene KIT. The variant is present in approximately 86% of Lewitzer horses with tobiano patterning, and has also been found in the Irish Cob.
