Overo

Overo patterning appears as white, jagged patches of largely varying sizes. It most commonly appears in horizontal orientation across the body and neck. These patches generally will not meet across the horse's dorsal line between the withers and tail, or under the belly, creating a "frame" of colour around the white. Face and head markings are common and often bold, such as full bald faces.

Overo may have isolated white spots, or holes within the white, but they should not be so small, clustered or even in shape as to resemble oduud or fryekli.

The geno code for Overo is written as:
nOv

Dominant Overo (OvOv) is not viable. Foals that receive two copies of the gene will be born solid white and pass away within hours.
