Meiosis and unequal cytoplasmic division
Web2 feb. 2024 · Meiosis Stages Diagram. Meiosis involves two successive stages or phases of cell division, meiosis I and meiosis II. Each stage includes a period of nuclear division or karyokinesis and a cytoplasmic division or cytokinesis. Although not a part of meiosis, the cells before entering meiosis I undergo a compulsory growth period called interphase. WebThis occurs, in fact, in a large number of higher organisms during meiosis —the process by which sex cells ( gametes) are formed: originally each chromosome of the cell is in a pair ( diploid ); during meiosis these diploid pairs of chromosomes are separated so that each sex cell has only one of each pair of chromosomes ( haploid ).
