Meiosis vs. Mitosis 1. Main: There are two kinds of cell division in eukaryotes. Mitosis is division involved in development of an adult organism from a single fertilized egg, in growth and repair of tissues, in regeneration of body parts, and in asexual reproduction. In mitosis, the parent cell produces two "daughter cells" that are genetically identical. Mitosis can occur in both diploid (2n) and haploid (n) cells. 2. Mitosis is the process by which a cell duplicates the chromosomes in its cell nucleus, in order to generate two, identical, daughter nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two daughter cells containing roughly equal shares of these cellular components. 3. Meiosis: A two-stage type of cell division in sexually reproducing organisms that results in cells with half the chromosome number of the original cell. 4. Meiosis I and II in Gametes a. Meiosis I i. Interphase: Chromosomes replicate (2 sister chromatids) and centrosome replicates ii. Prophase I: 90% time required, chromosomes condense, homologous chromosomes pair up precisely gene-by-gene.
