Detailed explanation-1: -In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.
Detailed explanation-2: -Answer and Explanation: The event that occurs in both anaphase of mitosis and anaphase II of meiosis is the separation of sister chromatids.
Detailed explanation-3: -It is in anaphase II, that the sister chromatids of the homologous pair finally separate and are pulled away from each other towards the opposite poles of the cell. Ultimately, in telophase II, the nuclear membranes reappear around each set of chromosomes, and these chromosomes undergo decondensation.
Detailed explanation-4: -Anaphase II: The chromatids split at the centromere and migrate along the spindle fibers to opposite poles. Telophase II: The cells pinch in the center and divide again. The final outcome is four cells, each with half of the genetic material found in the original. In the case of males, each cell becomes a sperm.
Detailed explanation-5: -Sister chromatids separate during anaphase in a three-stage program as directed by interaxis bridges.
