Vedclass · Answer

(A) In meiosis-$II$,the sister chromatids separate during anaphase-$II$ due to the splitting of the centromere. Similarly,in mitosis,the centromere splits during anaphase,allowing the sister chromatids to move toward opposite poles. Both processes are equational divisions where the centromere division is a key event. Therefore,both the Assertion and the Reason are correct,and the Reason correctly explains the mechanism involved in the Assertion.
