Detailed explanation-1: -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).

Detailed explanation-2: -Genetic variation is the presence of differences in sequences of genes between individual organisms of a species. It enables natural selection, one of the primary forces driving the evolution of life.

Detailed explanation-3: -Due to genetic and environmental factors, members of the same species will have different characteristics or variation. We measure and visualise variation based on whether it is continuous or discontinuous.

Detailed explanation-4: -Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation. Genetic variation is a result of subtle differences in our DNA?.
