Detailed explanation-1: -The sister chromatids then separate, and the microtubules pull them to opposite poles of the cell. As in mitosis, each chromatid is now considered a separate chromosome (Figure 6).
Detailed explanation-2: -Both mitosis and meiosis entail four main events: 1) a reproductive signal, 2) replication of nuclear DNA, 3) segregation of the replicated nuclear DNA into new daughter nuclei, and 4) division of the cytoplasm, or cytokinesis to produce new daughter cells.
Detailed explanation-3: -Sister chromatids are separated during anaphase of mitosis, and during anaphase II of meiosis.
Detailed explanation-4: -Homologue pairs separate during a first round of cell division, called meiosis I. Sister chromatids separate during a second round, called meiosis II. Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm).
