What's New In meiosis the cell goes through similar stages in mitosis and uses similar strategies to organize and separate chromosomes. However, the cell has a more complex task in meiosis. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. But it must also separate homologous chromosomes, the similar but non-identical chromosome pairs an organism receives from its two parents. These goals are accomplished in meiosis using a two-step division process. Homologue pairs separate during a first round of cell division, called meiosis I. Sister chromatids separate during a second round, called meiosis III. Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase. Stages of Meiosis I In meiosis I, homologous chromosomes are separated into two cells such that there is one chromosome (consisting of
