Tobiano

Tobiano is a spotted color pattern commonly seen in pinto horses, produced by a dominant gene.

Other spotting patterns seen in pinto horses include frame overo, splashed white and sabino.

[3] In some cases, a horse which carries both tobiano and overo genetics may display white markings that combine both patterns, and are referred to as toveros.

It is thought to be an ancient gene among domestic horses, about 3500 years old, and is widely distributed across many breeds in the world.

[4] After some years of research from the University of Kentucky, in 2008 the chromosomal inversion that affects regulatory regions of the KIT gene was discovered.
