Vedclass · Answer

(B) During spermatogenesis,the primary spermatocyte $(2n = 46)$ undergoes the first meiotic division (meiosis-$I$) to form two haploid secondary spermatocytes $(n = 23)$.Since meiosis-$I$ is a reductional division,the chromosome number is halved from the diploid state $(46)$ to the haploid state $(23)$.Therefore,a secondary spermatocyte contains $23$ chromosomes.
