Natural and artificial selection depend on genetic and phenotypic variation. In natural selection, the selective pressure comes from the environment, and in artificial selection it comes from the human breeder. Suppose a breeder of pigeons has a population of birds with feather pigments that range from light to intermediate to dark. She selectively breeds the pigeons with intermediate pigmentation. After several generations, which pattern of evolutionary change will be observed among the pigeons? A. disruptive selection, in which pigeons with dark pigmentation are favored. B. stabilizing selection, in which pigeons with intermediate pigmentation are favored. C. directional selection, in which pigeons with dark pigmentation are favored. D. directional selection, in which pigeons with intermediate pigmentation are favored.
