A grulla horse can indeed have white markings. Grulla is a coat color, not a breed, and while the base coat is typically a smoky or mouse-gray color, white markings such as socks or blazes can occur. These markings are determined by different genetic factors than the grulla color itself.
What Defines a Grulla Horse?
A grulla horse is recognized by its unique coat color, which is a dilution of the black gene. This results in a smoky or mouse-gray appearance, often accompanied by a dorsal stripe and other primitive markings like zebra stripes on the legs. The grulla color is a part of the dun gene family, which can also produce colors like red dun and classic dun.
How Are White Markings Inherited in Horses?
White markings in horses are typically inherited separately from coat color. They result from different genetic factors that can cause white patches, blazes, or socks. These markings can appear on any horse, regardless of its base coat color, including grullas.
- Genetic Influence: White markings are influenced by genes that control the distribution of pigment.
- Common Locations: White markings are often seen on the face and legs.
