Detailed explanation-1: -Genetic variation refers to differences among the genomes of members of the same species. A genome is all the hereditary information-all the genes-of an organism. For instance, the human genome contains somewhere between twenty and twenty-five thousand genes.

Detailed explanation-2: -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-3: -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-4: -Genetic diversity is the variation of genes within a particular species. Species diversity is the variation of species within a particular area. The main difference between genetic diversity and species diversity is the type of variation of each type of diversity.
