- Really? So, what kind of cells specifically go through that?
- Wait, what do you mean? like is there another type of cell division?
- Now, that's just one of the types of cell divisions that occur in our body.
- Precisely. Not all of the cells undergo mitosis, some cells go through a process called meiosis.
- Okay, I'm listening.
- That's interesting! I'm curious, how does meiosis differ from mitosis?
- Our germ cells or what we commonly known as our sex cells. So, to be specific, in females and males, their ovaries and sperms experience meiosis respectively.
- That's actually a very good question you have because to better understand meiosis, you ought to know first its difference with mitosis. Now, to answer your question, mitosis and meiosis differ in several ways.
- I already get it! I am eager to know more about their processes. Let's now get on with it when you're ready.
- Haha! As I have already said, meiosis is composed of Meiosis I and II, right? Okay, to start with, Prophase I start first. This stage is characterized mainly by the event of synapsis and crossing over. Homologous chromosomes pair with each other and exchange genetic information between non-sister chromatids thus responsible for genetic diversity.
- You already know that mitosis happens in body cells while meiosis in sex cells. Another difference is that meiosis is composed of two processes and instead of having to retain their number of chromosomes, it becomes reduced to half.
