In certain parts of Africa, where malaria is prevalent, there is a type of evolutionary pressure that keeps deadly recessive alleles in the population. This is because the heterozygous phenotypes have higher fitness. This is an example of: O Disruptive Selection Prezygotic Isolation Runaway Selection Stabilizing Selection

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.
