$S$ is true,but $R$ is false.

Vedclass · Answer

(C) Statement $S$ is true because meiosis is the specialized type of cell division that reduces the chromosome number by half,resulting in the production of haploid gametes (reproductive cells).Reason $R$ is false because,in meiosis,the genetic material $(DNA)$ replicates only once during the $S$-phase of interphase,while the cell undergoes two successive nuclear and cytoplasmic divisions (meiosis $I$ and meiosis $II$). Therefore,the correct answer is $C$.

List-$I$ (Phase of meiosis)	List-$II$ (Event that occurs)
$1$. Prophase $I$	Crossing over occurs
$2$. Metaphase $I$	Sister chromatids migrate to opposite poles
$3$. Anaphase $I$	Homologous chromosomes line up at the equator in pairs

$S$ - Statement: Meiosis occurs during the formation of reproductive cells. $R$ - Reason: During meiosis,the genetic material replicates twice,and the cell divides twice.
