Question 10: Distinguish anaphase of mitosis from anaphase I of meiosis.

Answer:

Anaphase of mitosis

Anaphase I of meiosis

Anaphase is the stage during which the centromere splits and the chromatids separate. The chromosomes move apart, toward the opposite poles. These chromosomes are genetically identical.

During anaphase I, the homologous chromosomes separate, while the chromatids remain attached at their centromeres.

Hence, in anaphase I, the chromosomes of each bivalent pair separate, while the sister chromatids remain together.

Anaphase of mitosis

Anaphase I of meiosis
