Answer:
option two "Genetic variation is differences in an organism's DNA leading to a variety of traits"
Option two is the correct answer because genetic variation refers to the differences in the DNA sequences of individuals within a population. This variation can lead to differences in physical traits, behavior, and other characteristics among individuals. Genetic variation is crucial for the survival and adaptation of a population to changing environmental conditions. Without genetic variation, populations may not have the necessary traits to survive changes in their environment, and may be more vulnerable to diseases or other threats.
Option B - Genetic variation is differences in an organism's DNA leading to a variety of traits.
