Sexual reproduction plays an important role in variation such that; production of unique gametes during meiosis, and the random combination of male and female gametes upon fertilization provides a large amount of variation (option A).
<h3>What is sexual reproduction?</h3>
Sexual reproduction is the process whereby a new organism is created by combining the genetic material of two organisms.
During sexual reproduction, organisms produce gametes through a process called meiosis.
This meiosis allows genetic diversity in the unique gametes produced, which causes random combination of male and female gametes upon fertilization provides a large amount of variation.
