Rabicano is a white pattern and sometimes classified as a modifier. It is one of the roaning colours and is sometimes referred to as ‘white ticking’. It is quite rare, but may appear in a wide range a breeds. The genetics behind rabicano are unknown and the appearance changes from horse to horse, but there are some tell-tale signs that can give it away.
The white hairs from rabicano are densely grouped on two locations:
- The horse’s flanks, close to its hindquarters. From there they spread out a little. Vertical white ‘stripes’ on the horse’s side resemble ribs.
- At the horse’s tailhead, often appearing as white ‘stripes’, called a skunk tail. More white hairs can be found in the area.
A horse with a very low expression of rabicano is difficult to identify, as only a few white hairs can be present. But extreme rabicano (which may be enhanced by a sabino phenotype) can result in so much white on the coat, the horse may resemble a greying horse or even a classic roan.
In the game rabicano is inherited as a recessive gene. Rabicano may be strengthened by sabino and other white pattern genetics. It is currently only present in the arabian and the akhal-teke and to make it a bit harder to select for, it only appears in adult horses.
