How is chromosome number maintained in mitosis? Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

WebAug 18, 2024 · Meiosis is a type of cell division whereby a diploid cell (somatic cell) undergoes two cell divisions, and divides to form four dissimilar haploid cells (sex cells). Diploid cells have two sets of chromosomes, where each chromosome has a homologous partner. Haploid cells only have one set of chromosomes. WebBoth start with diploid (2 sets of chromosomes) o Interphase occurs before both, duplicating chromosomes before division o Both mitosis and meiosis go through PMAT (prophase, metaphase, anaphase, telophase) Meiosis goes through PMAT twice (i.
