Vedclass · Answer

(C) Assertion $(A)$ is correct because meiosis is the specialized cell division that reduces the chromosome number by half,resulting in the production of haploid gametes (reproductive cells).Reason $(R)$ is incorrect because,in meiosis,the genetic material $(DNA)$ is replicated only once during the $S$-phase of interphase,although the cell undergoes two successive nuclear and cytoplasmic divisions (meiosis $I$ and meiosis $II$).

$A -$ During the formation of reproductive cells,meiotic cell division occurs.
$R -$ During meiosis,the genetic material is replicated twice and the cell divides twice.
