Final answer:
Sexual reproduction incorporates gametes from two parents to create a genetically unique offspring through meiosis and fertilization, resulting in a diploid zygote. The correct option is B) Two
Step-by-step explanation:
Sexual reproduction involves the function of cells, gametes, from two parents. These gametes are haploid cells, meaning they contain only half the number of chromosomes found in other cells of the organism.
Through a process called meiosis, gametes are produced by each parent. Fertilization occurs when two gametes unite, resulting in a zygote, which is a diploid cell containing twice the number of chromosomes as a gamete.
This cycle of sexual reproduction contributes to genetic diversity in offspring, providing an adaptive advantage in varying environmental conditions. The correct option is B) Two
