Short Answer

Solution

Genetic variation is the difference in DNA sequences between individuals within a population. Variation occurs in germ cells, i.e., sperm and egg, and also in somatic (all other) cells. Only variation that arises in germ cells can be inherited from one individual to another and so affect population dynamics, and ultimately evolution. Mutations and recombination are major sources of variation.
