Context: <response>: Mammalian hair, wey dem sabi as pelage, fit dey vary for color between populations, organisms within a population, and even on top di individual organism. Light-dark color variation dey common for mammalian taxa. Sometimes, dis color variation dey determined by age variation, but for other cases, e dey determined by other factors. Selective pressures, like ecological interactions with other populations or environmental conditions, dey often lead to di variation for mammalian coloration. These selective pressures dey favor certain colors to increase survival. Camouflage dey thought to be one major selection pressure wey dey shape coloration for mammals, although there dey evidence say sexual selection, communication, and physiological processes fit influence di evolution of coloration too. Camouflage na di most predominant mechanism for color variation, as e dey help to hide di organisms from predators or from their prey. Coat color fit also dey for intraspecies communication like warning members of their species about predators, indicating health for reproductive purposes, communicating between mother and young, and intimidating predators. Studies don show say for some cases, differences for female and male coat color fit indicate information about nutrition and hormone levels, wey dey important for di mate selection process. One final mechanism for coat color variation na physiological response purposes, like temperature regulation for tropical or arctic environments. Although much don dey observed about color variation, plenty of di genetic wey link coat color to genes still dey unknown. Di genetic sites wey pigmentation genes dey found dey affect phenotype by: 1) altering di spatial distribution of pigmentation of di hairs, and 2) altering di density and distribution of di hairs. Quantitative trait mapping dey used to better understand di distribution of loci wey dey responsible for pigmentation variation. However, although di genetic sites dey known, plenty still dey...
