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.

Detailed explanation-2: -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-3: -The individual members of a species also have differences in characteristics. For example, humans have different coloured eyes, and dogs have different length tails. This means that no two members of a species are identical. The differences between the individuals in a species is called variation.
