What Are the Stages of Meiosis, and How Do They Increase Genetic Variation?

Meiosis is a really interesting process! It happens in two main parts:

  1. Meiosis I: In this stage, similar chromosomes pair up and swap bits of genetic material. This swapping, known as crossing over, is super important because it helps create differences in genes. After these pairs are mixed up, they split into two separate cells.

  2. Meiosis II: This part is a lot like mitosis, which is another way cells divide. Here, the sister chromatids (which are copies of the chromosomes) are separated, leading to four different cells.

These stages help create genetic diversity. This means that instead of just making two identical cells, meiosis produces four unique gametes (or sex cells). It’s like nature’s way of stirring things up!
