    Splitting of centromere and hence separation of chromatids occur during

    A) anaphase of mitosis

    B) anaphase of meiosis-I

    C) anaphase of meiosis-II

    D) both [a] and [c]

    Correct Answer: D

    Solution :

    [d] During anaphase of mitosis, each chromosome arranged at metaphase plate is split and two daughter chromatids are formed. Centromeres split and chromatids move to opposite poles. During anaphase I of meiosis I, the homologous chromosomes separate, while sister chromatids remain associated at their centromeres. Anaphase 11 of meiosis II begins with simultaneous splitting of the centromere of each chromosome allowing them to move towards opposite poles of the cell.
