Answer 1

Variation:

1. Variation is defined as any difference among cells, individuals, or populations of any species that result from genetic variations (genotypic variation) or from the influence of environmental conditions on the expression of the genetic potentials (phenotypic variation).
2. Variations occur when the gametes of two parents fuse together.
3. Changes in the structure of DNA cause variation in organisms.
4. Metabolism, mode of reproduction, fertility, learning, behavior, and mental aptitude, and other measurable or evident characteristics may all show variation.

Final answer: Variation in organisms is due to changes in the structure of DNA.
