The document summarizes the processes of mitosis and meiosis. It describes the four phases of mitosis - prophase, metaphase, anaphase, telophase - and how the chromosomes behave in each phase. It then explains meiosis, which produces gametes through two rounds of cell division. Meiosis I involves synapsis, tetrad formation, and crossing over during prophase. Meiosis II is similar to a second mitosis that forms four haploid daughter cells from the two haploid cells produced in Meiosis I.
