Genetic Variation Definition, Causes, and Examples
Aug 21, 2019 · Genetic variation can be defined as the genetic makeup of organisms within a population change.Genes are inherited segments of DNA that contain codes for the production of proteins. Genes exists in alternate versions, or alleles that determine distinct traits that can be passed on from parents to offspring.

Natural selection occurs only if there is both (1) variation in the genetic information between organisms in a population and (2) variation in the expression of that genetic information—that is, trait variation—that leads to differences in performance among individuals. (HS-LS4-2) LS4.C: Adaptation

Evolution is a consequence of the interaction of four factors: (1) the potential for a species to increase in number; (2) the genetic variation of individuals in a species due to mutation and sexual reproduction; (3) competition for an environment’s limited supply of the resources that individuals need in order to survive and reproduce; and ...

Why genetic variation is important. Reduced genetic variation means that the population may not be able to adapt to new selection pressures, such as climatic change or a shift in available resources, because the genetic variation that selection would act on may have already drifted out of the population. Vocabulary. Genetic drift. Gene pool
