This process is divided into two halves, meiosis 1 and meiosis 2. Each of these contains four steps: first prophase, second metaphase, third anaphase, and fourth and last, telophase.

Web5 mrt. 2024 · In metaphase of mitosis and meiosis II, it is sister chromatids that line up along the equator of the cell.

WebIt occurs only before Meiosis I. there is no interphase between Meiosis I and Meiosis II. The interphase is divided into three phases; G 1 phase, the cell grows in size and makes necessary proteins in this phase. S phase, the cell undergoes DNA replication. G 2 phase, the cell makes proteins that are needed for meiosis. WebMeiosis begins following one round of DNA replication in cells in the male or female sex organs. The process is split into meiosis I and meiosis II, and both meiotic divisions …

WebMEIOSIS I: Homologous chromosomes separate.
