An agouti dog, also called wolf sable. In dogs, the agouti gene is associated with various coat colors and patterns. [10]The alleles at the A locus are related to the production of agouti-signaling protein (ASIP) and determine whether an animal expresses an agouti appearance and, by controlling the distribution of pigment in individual hairs, what type of agouti.
A cat hair showing agouti coloration A domestic rabbit with agouti coloration. Agouti is a type of fur coloration in which each hair displays two or more bands of pigmentation. [1] [2] The overall appearance of agouti fur is usually gray or dull brown, [3] although dull yellow is also possible.
The colorpoint pattern is most commonly associated with Siamese cats, but due to crossbreeding may also appear in any (non-pedigree) domesticated cat. A colorpoint cat has dark colors on the face, ears, feet, and tail, with a lighter version of the same color on the rest of the body, and possibly some white.
Cats are limited in their perception of color. Human eyes have 10 times more cone cells than feline eyes, meaning we can see a larger range of colors than cats, according to Purina.
However, the agouti gene primarily controls the production of black pigment, so a cat with an O allele for orange color will still express the tabby pattern. As a result, both red cats and the patches of red on tortoiseshell cats will always show tabby patterning, though sometimes the stripes are muted—especially in cream and blue/cream cats ...

Agouti-signaling protein is a protein that in humans is encoded by the ASIP gene. [5] [6] It is responsible for the distribution of melanin pigment in mammals.[7] [8] Agouti interacts with the melanocortin 1 receptor to determine whether the melanocyte (pigment cell) produces phaeomelanin (a red to yellow pigment), or eumelanin (a brown to black pigment).
