Vedclass · Answer

(A) In Meiosis-$I$,the homologous chromosomes separate and move to opposite poles,while the sister chromatids remain attached at the centromere.Because the homologous pairs separate,the number of chromosomes in each daughter cell is reduced to half compared to the parent cell.Therefore,Anaphase-$I$ is indeed the phase where the reduction in chromosome number occurs.The Reason statement correctly describes the movement of homologous chromosomes to opposite poles with their chromatids intact.Thus,both statements are correct,and the Reason explains why the chromosome number is reduced.

$A$ : Anaphase-$I$ is the actual phase of reduction in the number of chromosomes.
$R$ : Homologous chromosomes move to the opposite poles with both their chromatids.
