Question

Quizplus · Accepted Answer

During meiosis, the diploid cell undergoes two rounds of division, resulting in four haploid cells. In the first round of division, homologous chromosomes pair up and exchange genetic material, crossing over. Then, the chromosomes separate, resulting in two cells that each have half the number of chromosomes as the original diploid cell. In the second round of division, the sister chromatids of each chromosome separate, resulting in four haploid cells. Therefore, each gamete would have 9 chromosomes, which is half of the original diploid cell's 18 chromosomes.
