Vedclass · Answer

(C) Assertion $(A)$: In meiosis $I$,during anaphase $I$,the homologous chromosomes separate and move to opposite poles. This statement is correct.Reason $(R)$: In anaphase $I$,the homologous chromosomes separate,but the sister chromatids remain attached at the centromere. Therefore,each pole receives a complete set of chromosomes (each consisting of two chromatids),not half the number of chromatids. The reduction in chromosome number occurs,but the number of chromatids per chromosome remains the same as the parent cell at the start of division. Thus,the statement that each pole receives half the number of chromatids is incorrect.Therefore,$A$ is correct and $R$ is incorrect.

$A-$ In meiosis,during anaphase $I$,homologous chromosomes move to the opposite poles.
$R-$ Each pole receives half the number of chromatids in anaphase $I$.
