The red-rumped agouti (Dasyprocta leporina), also known as the golden-rumped agouti, orange-rumped agouti or Brazilian agouti, is a species of agouti from the family Dasyproctidae. Distribution [ edit ]
The crested agouti (Dasyprocta cristata) is a species of rodent in the family Dasyproctidae. It is found in Guyana and Suriname . [ 1 ] Its taxonomic status is uncertain and it may be synonymous with Dasyprocta leporina , leading the IUCN to rate it as Data Deficient .

The population is unknown and may have gone locally extinct in some areas due to hunting; it is listed as vulnerable in Argentina.
Agouti (coloration), fur coloration in which each hair has alternating dark and light bands; Agouti-signalling protein or ASIP, a circulating hormone encoded by the agouti gene that acts as an antagonist at melanocortin receptors; Agouti-related peptide, a neuropeptide produced in the brain by the AgRP/NPY neuron
White-bellied agouti A W mice have agouti coloration, with hairs that are black at the tips, then yellow, then black again, and white to tan bellies. [4] Agouti A looks like A W but the belly is dark like the back. [4] Black and tan a t causes a black back with a tan belly. A/a t heterozygotes look like A W mice. [4]
Extension is epistatic to agouti, meaning that if a horse has two e alleles, it will be chestnut no matter what genotype it has at agouti. [10] [11] The agouti gene codes for a molecule called the agouti-signaling protein, or ASIP. This molecule interacts with MC1R, the receptor coded by extension, to block the signal for black pigment ...
