WebMar 24, 2011 · The two-stage process of meiosis begins with meiosis I, also known as reduction division since it reduces the diploid number of chromosomes in each daughter cell by half. This first step is further subdivided into four main stages: prophase I, metaphase I, anaphase I, and telophase I.

WebAs in mitosis, the cell grows during G _1 1 phase, copies all of its chromosomes during S phase, and prepares for division during G _2 2 phase. During prophase I, differences from mitosis begin to appear. As in mitosis, the chromosomes begin to condense, but in … WebThe homologous chromosomes separate into different nuclei during meiosis I, causing a reduction of ploidy level in the first division. The second division of meiosis is more similar to a mitotic division, except that the …
