Question

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

• A. Spermatogonia ---> Spermatocyte ---> Spermatid ---> Sperms
• B. Spermatid ---> Spermatocyte ---> Spermatogonia ---> Sperms
• C. Spermatogonia ---> Spermatid ---> Spermatocyte ---> Sperms
• D. Spermatocyte ---> Spermatogonia ---> Spermatid ---> Sperms

Answer 1

Answer: (A)

Spermatogonia ---> Spermatocyte ---> Spermatid ---> Sperms

Spermatogenesis is the process which takes place in the testes and involved in the production os the sperms. The germ cells or spermatogonia divide mitotically to yield primary spermatocyte which divides meiotically into two secondary spermatocytes. Each of the secondary spermatocytes divides into two spermatids by meiosis II. These develop into mature sperm cells.
Therefore, the correct answer is option A.
