Overview of MeiosisMeiosis is a two-part cell division process in organisms that sexually reproduce. Meiosis produces gametes with one half the number of chromosomes as the parent cell. In some respects, meiosis is very similar to the process of mitosis, yet it is also fundamentally different.
The two stages of meiosis are meiosis I and meiosis II. At the end of the meiotic process, four daughter cells are produced. Each of the resulting daughter cells has one half of the number of chromosomes as the parent cell.
Before a dividing cell enters meiosis, it undergoes a period of growth called interphase.
During interphase the cell increases in mass, synthesizes DNA and protein, and duplicates its chromosomes in preparation for cell division.
Meiosis I encompasses four stages:
- Prophase I
- Metaphase I
- Anaphase I
- Telophase I
Meiosis II encompasses four stages:
- Prophase II
- Metaphase II
- Anaphase II
- Telophase II
