In which phase(s) of cell division do we observe splitting of the centromere of each chromosome which is holding the sister chromatids together?
(a) Metaphase of mitosis
(b) Anaphase I of meiosis
(c) Anaphase of mitosis
(d) Anaphase II of meiosis

Splitting of centromere of each chromosome which was holding the sister chromatids together is seen in anaphase of mitosis and in anaphase II of meiosis. In anaphase I of meiosis the homologous chromosomes separate, while sister chromatids remain associated at their centromeres.
