Answer:
During mitosis, the number of chromosomes remains the same in both diploid and haploid cells. Diploid cells have two sets of chromosomes (2n), while haploid cells have only one set (n). During meiosis, the number of chromosomes is reduced by half, with diploid cells producing four genetically different haploid cells. Meiosis also involves recombination and independent assortment of homologous chromosomes during meiosis I, followed by separation of sister chromatids during meiosis II.
