Tobiano (pinto or piebald/skewbald)

Why test for tobiano?

Tobiano, a type of pinto also known as piebald (black and white) or skewbald (other colours and white), is a striking equine spotted coat colour pattern. 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 gene variant that causes tobiano colouring, or two (there is no visual difference but those that have two copies will pass this pattern on to all their foals). It is also very useful when you suspect your horse or pony may carry multiple white pattern genes.
