Allele frequency refers to the fraction of individuals with a particular version of a given gene.What effect does natural selection have on the allele frequency of a population?    A.  It causes the allele frequency to resemble that of a small number of individuals that became separated from the rest of the population.  B.  It causes random changes and the allele frequency of certain traits may increase or decrease.  C.  It increases the frequency of alleles that improve a species' survival in a particular environment.  D.  It greatly reduces the total population, which increases the effects of genetic drift on allele frequency.

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
