In both mitosis and meiosis ii
WebThe mechanics of meiosis II are similar to mitosis, except that each dividing cell has only one set of homologous chromosomes, each with two chromatids. Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis. 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 …

WebMeiosis I reduces ploidy from 2n to n (reduction), whereas Meiosis II divides the remaining chromosomes in a mitosis-like process (division). Meiosis produces four daughter cells that are haploid and genetically different. Mitosis produces diploid offspring cells that are identical to the parent cell. 3. WebThe purpose of mitosis is cell regeneration, growth, and asexual reproduction,while the purpose of meiosis is the production of gametes for sexual reproduction. Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into …
