Detailed explanation-1: -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-2: -Variation refers to the differences or deviations from the recognized norm or standard. It may be a modification in structure, form or function in an organism, deviating from other organisms of the same species or group.
