What is Meiosis? Meiosis is a type of cell division and it reduces halfs the chromosones. One parent cell splits into two. There are 4 stages: Interphase, Prophase, Metaphase, Anaphase and Telephase. What interphase does is that the cell spends a lot of his life replicating the DNA. Prophase is when the DNA and proteins in the nucleus condense. Metaphase is when they align themselves in the middle of the cell. In Anaphase, what happens is that they seperate into four identical cells. In telephase, which is the final stage of meiosis, and what happens is that after it splits, the cells start becoming identical. In meiosis, it turns two diploid cells to haploid cells. The difference between meiosis and mitosis is that meiosis is sexual and mitosis isn't. Meiosis also splits into four daughter cells while mitosis only spits into two.
