Vedclass · Answer

(C) $1$. Spermatogonia $(P)$ are diploid cells formed by mitosis in the testes,so they contain $46$ chromosomes.$2$. Primary spermatocytes $(Q)$ are formed from spermatogonia by differentiation without division,so they remain diploid and contain $46$ chromosomes.$3$. Spermatids $(R)$ are formed after the completion of Meiosis-$I$ and Meiosis-$II$,making them haploid cells,so they contain $23$ chromosomes.$4$. Therefore,the chromosome numbers are $P=46$,$Q=46$,and $R=23$.

The schematic representation of spermatogenesis is given below. How many chromosomes do $P$,$Q$,and $R$ contain?
$P$ (Spermatogonia) $\rightarrow$ $Q$ (Primary Spermatocyte) $\rightarrow$ $R$ (Spermatid)
