Differences between meiosis I and meiosis II Grade 12 Life Sciences Notes with Activities Questions and Answers Understanding the process of meiosis is crucial, especially for students delving into Grade 12 Life Sciences. Meiosis, the specialized cell division process that produces gametes, involves two distinct stages: meiosis I and meiosis II. While both stages share similarities, they also exhibit significant differences. In this blog post, we’ll delve into the disparities between meiosis I and meiosis II, accompanied by engaging activities, questions, and answers tailored for Grade 12 learners.
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. |
