Vedclass · Answer

(D) In the process of spermatogenesis,the primary spermatocyte undergoes meiosis-$I$ to form two equal haploid cells called secondary spermatocytes.Therefore,the first haploid cells formed during spermatogenesis are secondary spermatocytes,not spermatids.Thus,Assertion $(A)$ is incorrect.At the end of meiosis,the chromosome number is reduced to half,making the cells haploid. Therefore,Reason $(R)$ is correct.Since Assertion $(A)$ is incorrect and Reason $(R)$ is correct,the correct option is $(D)$.

$A$: In spermatogenesis,the first haploid forms are spermatids.
$R$: At the end of meiosis,cells have a haploid set of chromosomes.
