WebMeiosis (shown in Figure 2.9) entails two cell divisions. In the first division, homologous chromosomes (e.g., the chromosome 3 pair in the diploid cell) come together and are then separated into different cells. Hence, the … WebMeiosis, like mitosis, begins with replication to produce pairs of sister chromatids connected by cohesion (Figure 1Bii).Then, in contrast to mitosis, a single copy of every chromosome must be accurately distributed to four different nuclei.
