Mutations can sometimes be advantageous by making the organism better adapted to its environment.

Mutations can sometimes be advantageous by making the organism better adapted to its environment.

• A. False
• B. Sometimes
• C. True
• D. Not Applicable

Answer: (C)

Mutations generate genetic variation that serves as the raw material for evolution. Some changes in DNA alter traits in a way that improves an organism’s survival or reproductive success in a given environment, making that mutation advantageous. Whether a mutation is beneficial depends on the environment and the trait affected, so benefits are context-specific rather than universal. Because natural selection favors traits that enhance fitness, beneficial mutations can increase in frequency and lead to adaptation. It’s important to remember that many mutations are neutral or deleterious, but the idea that some mutations can be advantageous is well supported. For example, a mutation that confers antibiotic resistance can be highly advantageous in the presence of the antibiotic. Overall, the statement is true.
