Correct answer is genetic variation.
Individuals must survive to reproduce, produce fertile offspring, and pass their genes on to future generations.
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
