Explanation: 

Detailed explanation-1: -Which of the following statements BEST explains the role of meiosis in reproduction? Meiosis increases the chances of fertilization because it produces four daughter cells.

Detailed explanation-2: -Which of the following statements best explains the role of meiosis in reproduction? Meiosis makes it possible for a zygote to have the correct number of chromosomes.

Detailed explanation-3: -So, the correct answer is ‘Meiosis produces gametes that contain one complete haploid set of chromosomes’

Detailed explanation-4: -The statement that best describes meiosis is C. separation of sister chromatids.

Detailed explanation-5: -In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. The haploid number is produced during meiosis.
