e high frequency l anemia, in areas with high incidence of malaria suggests that: Individuals that are heterozygote of sickle-cell anemia were retained in the population due to their fitness advantage against malaria. The retaining of individuals with the autosomal recessive disease is an example of purifying selection The retaining of individuals with the autosomal recessive disease is an example of directional selection O natural selection is not true because individuals with the devastating disease is retained in the population. Malaria causes sick-cell anemia.

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.
