WebMeiosis can be divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II): Meiosis I 1. Interphase: The DNA in the cell is copied resulting in two identical full sets of chromosomes.
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 …
WebOct 27, 2024 · In the first stage – meiosis I – a single cell divides into two daughter cells, each containing 23 pairs of chromosomes or 46 chromosomes. In meiosis II, these two daughter cells split again, this time each containing 23 chromosomes, not chromosome pairs.
