Concept 13.3: Meiosis reduces the number of chromosome sets from diploid to haploid * Like mitosis, meiosis is preceded by the replication of chromosomes * Meiosis takes place in two consecutive cell divisions, called meiosis I and meiosis II * The two cell divisions result in four daughter cells, rather than the two daughter cells in mitosis * Each daughter cell has only half as many chromosomes as the parent cell The Stages of Meiosis * Chromosomes duplicate before meiosis * The resulting sister chromatids are closely associated along their lengths * This is called sister chromatid cohesion * The chromatids are sorted into four haploid daughter cells * Division in meiosis I occurs in four phases: Prophase I
