Without genetic variation, a population cannot evolve in response to changing environmental variables and, as a result, may face an increased risk of extinction. For example, if a population is exposed to a new disease, selection will act on genes for resistance to the disease if they exist Genetic variation among humans occurs on many scales, from gross alterations in the human karyotype to single nucleotide changes.
