WebNatural selection acts on the phenotype, the characteristics of the organism which actually interact with the environment, but the genetic (heritable) basis of any phenotype that gives that phenotype a reproductive advantage may become more common in a population. WebA. Natural Selection occurs because some alleles confer higher fitness, whereas genetic drift occurs because of sampling error. B.
