Which statement correctly relates natural selection and variation?
Answer and explanation
Correct answer: Natural selection can increase favourable traits among variations
Variation means that individuals of the same species differ in their inherited features. Natural selection acts on these differences: if a variation helps an organism survive or reproduce in a particular environment, that organism may leave more offspring. Over many generations, the favourable inherited trait can become more common. Thus A is correct; selection does not remove every variation and does not transmit acquired traits directly.
