a. In humans, both meiosis and mitosis start with a cell that has duplicated chromosomes. Remember, cells duplicate their DNA during S phase in the cell cycle; this happens prior to meiosis or mitosis. Meiosis includes two rounds of cell division, whereas mitosis only has one. As a result, cells that arise from meiosis have chromosomes and cells that arise from mitosis have chromosomes.
