Detailed explanation-1: -Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing environmental circumstances.

Detailed explanation-2: -Variation in the genes of an organism within a species or between the population of same species is called genetic diversity.

Detailed explanation-3: -Genetic variations can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell is getting ready to divide (known as genetic recombination). Genetic variations that alter gene activity or protein function can introduce different traits in an organism.

Detailed explanation-4: -A person’s skin color, hair color, dimples, freckles, and blood type are all examples of genetic variations that can occur in a human population. Examples of genetic variation in plants include the modified leaves of carnivorous plants and the development of flowers that resemble insects to lure plant pollinators.

Detailed explanation-5: -Genetic variation deals with individuals of a particular species, whereas genetic diversity could be related to either one or more species. Genetic variation mainly takes place due to sexual reproduction and mutations, while genetic diversity becomes important for the demands of nature.
