Answer: Unlike mitotic cells, meiotic cells undergo two divisions to produce haploid cells, allowing for genetic diversity in sexually reproducing organisms.
Explanation:
Both meiosis and mitosis are types of cell division. However, unlike mitosis that occur at one division only and yield two daughter cells with diploid number; meiosis involves two division steps:
- Meiosis I
where the parent cell is halved in chromosome number, and genetic materials are mixed between chromatids
-Meiosis II
where the two daughter cells generated in meiosis I is further divided into four haploid cells.
