Which coat pattern can be identified by having no white markings on the legs?

The coat pattern known as overo is characterized by distinct features, one of which is the absence of white markings on the legs. This pattern typically manifests with irregular, jagged white patches that often do not cross the back of the horse, resulting in a distinctive appearance. Overo horses can have a variety of other colors, but the key trait is that the white does not extend down to the legs, keeping them solid-colored.

In contrast, tobiano horses usually exhibit white markings that cross over the back and extend down the legs, creating a different visual appearance. Splash patterns can have white markings that often extend from the belly up to the legs, sometimes giving a "splash" effect, while tovero is a combination of tobiano and overo traits, often featuring white on the legs but also including the distinct markings of the overo pattern. Therefore, since overo is specifically defined by having no white on the legs, this makes it the correct choice for identifying the coat pattern described.
