Question

members of a population of guinea pigs exhibit one of three possible coat colors: black, gray, or white. due to habitat loss, the population has recently colonized a new environment that has areas of black rocks as well as areas of white rocks. in addition, this new habitat contains several predators. if you could visit this population several generations later, what kind of phenotypic pattern, in terms of coat color, would you expect to find in this population? multiple choice most guinea pigs would be gray. most guinea pigs would be black. most guinea pigs would be white. there would be no difference in the frequency of coat colors. most guinea pigs would be either black or white.

Explanation:

Guinea pigs with coat colors that match the new habitat's rock colors (black or white) will have a survival advantage as they can better camouflage from predators. Over generations, natural selection will favor these phenotypes, leading to an increase in the frequency of black - and white - coated guinea pigs.

Answer:

Most guinea pigs would be either black or white.
