The type of selection which is likely to occur on the following phenotypes:
Stabilizing selection: grey fur
Diversifying selection: dark fur on island and light on another island. Dark fur in forests and light in fields
Directional selection: dark and light fur
When individual people with such character traits generate more surviving offspring than individual people with other characteristics, this is referred to as phenotypic selection. Although selection is widely regarded as the primary driver of evolutionary change, scientists have only lately started to quantify its effects in the wild.
Because phenotype influences differential reproduction and survivorship, selection acts on phenotypes. If the phenotype influencing reproduction or survival rates is genetically determined, selection can indirectly winnow out genotypes by winnowing out phenotypes.
