What is the importance of greater variation in sexual reproduction for evolution?
Answer and explanation
Correct answer: It provides more variation for natural selection to act upon
The governing concept is variation as the raw material for natural selection. Sexual reproduction combines genetic information from two parents through meiosis and fertilisation, producing new combinations of traits. If environmental conditions change, some variants may survive or reproduce more successfully than others, allowing populations to evolve over generations. Therefore A is correct. The other options describe outcomes opposite to the role of sexual reproduction.
