Variation: variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).

Two models to explain genetic variation in populations an important question in population genetics is how much genetic variation can exist in a population or a species.
