Color: Agouti is an alternating pattern of black and yellow on the hair shaft, ending in a black tip. Solid coloring (also known as self-colored) produces a hair shaft with only one color.

Samples Accepted: Blood, Buccal Swabs

Locus Information: A
Agouti coloration in the cat is dominant, and consists of an alternating pattern of black and yellow on each hair shaft, ending with a black tip. Solid coloring is recessive, and the color is uniform on the hair shaft. A solid animal may still have tabby patterning, as it is controlled by another locus (T), but this may be difficult to see with the eye.

Test Information: This mutation test identifies a 2 base pair deletion in the ASIP gene, which is responsible for solid coloring in all cats.
