Which statement best describes how natural selection affects the genetic equilibrium of a population? Differences in the survival and reproductive success of individuals carrying different genotypes alter allele frequencies. The deletion or modification of alleles alters the gene pool of a population. Due to chance, allele frequencies fluctuate from one generation to the next. Allele frequencies are altered due to alleles moving into or out of populations as individuals migrate between them.
Suman K.
Genetic drift Evolutionary change within a population. Complete the following paragraph to describe agents that do not necessarily cause random changes in the allele frequencies of a gene pool, but rather changes in the environment that affect gene flow. These events can include disease, famine, and selection. Because of this, these events can impact the adaptation of the population to the environment. Although genetic drift occurs in populations of all sizes, its effect is greatest in smaller populations.
