WebMeiosis consists of two rounds of chromosome segregation following a single replication. The phases of meiosis is divided into two; meiosis-I and meiosis-II. Before the onset of meiotic division, the chromosomes of the pre-gametic cell are replicated to yield two pairs of sister chromatids after which they enter a long meiotic prophase interval.
