points are the slowest areas of the body to go gray. Point coloration may also be visible on horses with other dilution genes that act upon a bay base coat. These include: The cream gene, an incomplete dominant, that when heterozygous produces Buckskin. When homozygous, even point coloration is mostly suppressed, the color is called perlino, and some individuals may have slightly redder hair at the traditional point coloration locations. The Champagne gene, which on a bay base produces Amber Champagne. A dilution gene that produces what looks like point coloration, but from a completely different genetic mechanism is the dominant Dun gene, which dilutes the color of the body coat but not the points, including primitive markings—a dorsal stripe down the back and, less often, horizontal striping on the upper legs. On a bay base coat the dun gene leaves black points, producing a Bay Dun or "Zebra" Dun. But the gene also leaves the points dark when it appears with other base colors. These include the “blue dun” or grullo, which has a black base coat, and the red dun, which has a chestnut base coat. Similarly, darker coloration at the points is also preserved in horses with the roan gene, a patterning gene, producing a body coat of mingled white and dark hairs, but leaving the points the darker base color in all horses, not just those carrying agouti. Most other genes that produce spotting patterns or white markings allow point coloration produced by agouti to show except where masked by white depigmentation. There are not always separate names for a pattern over a bay base coat, but one exception is the Bay pinto, sometimes called ”tricoloured”. In rabbits and rodents All pointed white rabbits of true breeding have red eyes. The pointed white rabbit is created with the ch gene. Its presentation is typified in the Himalayan rabbit breed (the first rabbit breed with a pointed white coat) and in the Californian breed. Rabbit coat colors Some rabbits that appear to be pointed white lack the red eyes, which indicates they are of different breeding. The following such coat colors are examples of those created, not with the ch gene, but with the cchl, cchd, or cchm gene in conjunction with the e gene: Blue point Chocolate point Lilac point Pearl Sable point Sallander Seal point Siamese No pointed white rabbit can produce orange pigment; therefore,
