WebThe combined cytokinesis and pre-meiosis 2 prep phase is sometimes called interkinesis. Interkinesis differs from interphase in the fact that there is no DNA replication between meiosis 1 and 2. Meiosis produces genetically unique daughter cells. Homologous chromosomes separate in meiosis 1 and sister chromatids separate during meiosis 2. Web18 aug. 2024 · Meiosis is the type of cell division used to produce gametes or sex cells (sperm and egg cells). A cell undergoing meiosis will divide twice - the first division is meiosis I and the second is meiosis II.
