During prophase I, chromosomes pair up and exchange genetic material, creating more variation. In metaphase I, chromosomes line up in the middle of the cell. Anaphase I separates homologous pairs, while telophase I forms two new cells with a haploid number of chromosomes.

It starts with prophase II, where the nuclear envelope dissolves and chromosomes condense. Then, in metaphase II, chromosomes line up along the cell's middle. During anaphase II, sister chromatids separate and move to opposite ends of the cell. Finally, in telophase II, the nuclear envelope reforms, and the cell splits into four new cells, each with a haploid number of chromosomes.
