We are taking a break from April 13-19. We will be back the following week.

DNA testing for health, appearance and pedigree verification in horses

Learn about one of the tests we do: Tobiano

The tobiano pattern is often referred to as pinto, piebald (black and white) or skewbald (other colours and white). The tobiano gene produces white patches with pink skin - usually large, smooth-edged patches - on a different base coat colour.

Genetic testing for tobiano can tell you whether your horse has one copy of the tobiano gene or two (visual differences are not always present). It is also very useful when you suspect your horse or pony may carry multiple white pattern genes.

Gene or region and technical reference

Gene: inversion downstream of KIT (causative). Reference: Brooks et al. (2007)
