A ticked tabby cat (sometimes called Abyssinian tabby or agouti tabby) does not have the traditional stripes or spots on her body, and may not, at first, seem to be a tabby. The agouti gene, A/a which codes for agouti signaling protein.The dominant, wild-type A causes the agouti shift phenomenon which causes hairs to be black pigmented at the tips and orange pigmented at the roots (revealing the underlying tabby pattern), while the recessive non-agouti or "hypermelanistic" allele, a, prevents this shift in the pigmentation pathway. The agouti gene, A/a, [4] controls whether or not the tabby pattern is expressed. A ticked tabby cat (sometimes called Abyssinian tabby or agouti tabby) does not have the traditional stripes or spots on her body, and may not, at first, seem to be a tabby. The Abyssinian is a muscular and athletic cat of medium build with regal airs belying its curious nature and eagerness to play. Classification of these can be confusing sometimes because different registries or associations may name the same phenotype differently.

Albino: A cat devoid of pigment. Residual ghost striping or " barring " can often be seen on the lower legs, face and belly and sometimes at the tail tip.

Agouti, (genus Dasyprocta), any of about a dozen species of tropical American rodents resembling the small forest-dwelling hoofed animals of tropical Africa and Asia (see chevrotain; duiker; royal antelope). Agouti definition, any of several short-haired, short-eared, rabbitlike rodents of the genus Dasyprocta, of South and Central America and the West Indies, destructive to sugar cane. It is responsible for the distribution of melanin pigment in mammals. So, Orange cats will always express Agouti, even if its genetic code says it is aa and should be self-colored. Agouti hairs The Ticked tabby pattern produces agouti hairs , hairs with distinct bands of color on them, breaking up the tabby patterning into a salt-and-pepper appearance. Below is a table of the coat color genes and DNA tests offered by the Veterinary Genetics Laboratory. The Agouti Signaling Protein (ASIP) gene interacts with the MC1R gene to control red and black pigment switching in most mammals including dogs.Dog coat color is further complicated by the interaction of other genes that restrict agouti expression such as the Dominant Black gene/K Locus (Beta-Defensin 103).

Agoutis weigh up to 6 kg (13 pounds), with an elongated

Agouti-signaling protein is a protein that in humans is encoded by the ASIP gene.

In the agoutidae family.
