Differences Between Meiosis I and Meiosis II Grade 12 Life Sciences Notes
What is the difference between meiosis 1 and meiosis 2?
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate.
Below is the table which shows the difference between Meiosis I and Meiosis II
| Meiosis i | Meiosis ii |
| The chromosomes arrange at the equator of the cell in homologous pairs. | Chromosomes line up at the equator of the cell individually. |
| Whole chromosomes move to opposite poles of the cell. | Daughter chromosomes/chromatids move to opposite poles of the cell. |
| Two cells form at the end of this division | Four cells are formed at the end of this division. |
| The chromosome number is halved during meiosis I | The chromosome number remains the same during meiosis II. |
| Crossing over takes place. | Crossing over does not take place. |
