Correct answer: "Genetic variation is differences in an organism's DNA, leading to a variety of traits."
Why the others are wrong:
- Genetic variation can benefit, harm, or have no effect on an organism depending on the environment, so it is not always beneficial.
- Variation is not chosen by the organism; it arises from mutations, recombination, and the random combination of parental genes.
- Variation does not occur when parents give identical genes; it arises because parents usually pass different combinations of alleles to offspring.
