261:, may be responsible for the most familiar expressions of white: heterozygotes possessing common-size "blankets" and homozygotes possessing extensive "blankets" that may affect the entire coat. Even horses with extensive white usually retain dark colored regions just above the hooves, on the knees and hocks, stifles and elbows, hips and points of shoulder, the tail, mane, and the bony parts of the face. The smallest amount of white patterning is just a sprinkling of white over the hips. 825: 577: 426: 486: 456: 22: 544: 244: 844:" in a cave in France depict spotted horses with a leopard pattern. Archaeologists had debated over whether the artists were painting what they saw or whether the spotted horses had some symbolic meaning.

Furthermore, a certain amount of this inherited white patterning is present at birth. The amount of white, even if none is present at birth, often grows throughout the horse's life by gradual "roaning" which is not related to 1535: 411: 307: 512: 527: 270: 584:
