Question

The correct sequence of spermatogenetic stages leading to the formation of sperms in a mature human testis is

• A. Spermatocyte$\to$Spermatogonia $\to$Spermatid$\to$Sperms
• B. Spermatogonia $\to$Spermatocyte $\to$Spermatid $\to$Sperms
• C. Spermatid $\to$Spermatocyte $\to$ Spermatogonia$\to$Sperms
• D. Spermatogonia$\to$Spermatid $\to$Spermatocyte$\to$Sperms

Answer 1

The correct option is B Spermatogonia $\to$Spermatocyte $\to$Spermatid $\to$Sperms

The germ cells undergo mitosis and forms group of cells which are known as spermatogonia. Spermatogonia is diploid and undergoes mitosis to form primary spermatocyte which further undergoes meiosis to form haploid secondary spermatocyte. The secondary spermatocyte undergoes meiosis II to form haploid spermatids. The spermatids get transformed into spermatozoa by the process of spermiogenesis to form active sperms.
Therefore, the correct answer is option B.
