For natural selection to occur within a population, there must be phenotypic variations that are genetic, meaning they are inherited. These variations allow some individuals to have higher fitness and survive better in their environment, passing on their advantageous traits to their offspring. This process leads to a change in the genetic makeup of the population over time. Phenotypic differences resulting from environmental conditions (A) can be important in shaping phenotypic variation but are not enough for natural selection to occur. While mutations (B) can provide new genetic variation, they do not necessarily occur frequently or always result in advantageous traits. Immigration rates (C) can affect the genetic makeup of a population, but they are not necessary for natural selection. Heterozygosity (E) refers to the presence of different alleles within an individual, but it is not a necessary condition for natural selection to occur.
