Why does sexual reproduction produce more variation?
Answer and explanation
Correct answer: Because genetic information from two parents combines
The governing concept is genetic recombination in sexual reproduction. Each parent contributes a set of genes through a gamete, and fertilisation combines genetic material from two individuals. Meiosis and the random union of gametes create new combinations of alleles, so offspring are not genetically identical to either parent or usually to one another. Therefore option A is correct; the other statements describe or imply asexual reproduction incorrectly.
