WebMetaphase. After prophase, the cell begins metaphase. The main event during this phase is chromosomes lining up along the center of the cell. This prepares the cell for the next phase. It's important to remember that each chromosome consists of two sister chromatids. The chromatids are connected in the middle by a centromere. WebMeiosis is the process in which a single cell divides twice to form four haploid daughter cells. These cells are the gametes – sperms in males and egg in females. The process of meiosis is divided into 2 stages. Each stage is subdivided into several phases.

WebMeiosis I. Meiosis is preceded by an interphase consisting of G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase (the “first gap phase”) is focused on cell growth. During the S phase—the second phase of interphase—the cell copies or replicates the DNA of the chromosomes. WebMeiosis consists of two divisions, both of which follow the same stages as mitosis (prophase, metaphase, anaphase, telophase) Meiosis is preceded by interphase, in which DNA is replicated to produce chromosomes …
