Question

Which is the correct sequence in spermatogenesis?

• A. Spermatogonia $\to$ Spermatids $\to$ Secondary spermatocytes $\to$ Primary spermatocytes $\to$ sperms
• B. Spermatogonia $\to$ Spermatids $\to$ Primary spermatocytes $\to$ Secondary spermatocytes $\to$ Sperms
• C. Primary spermatocytes $\to$ Secondary spermatocytes $\to$ Spermatids $\to$ Spermatogonia $\to$ Sperms
• D. Spermatogonia $\to$ Primary spermatocytes $\to$ Secondary spermatocytes $\to$ Spermatids $\to$ Sperms

Answer 1

The correct option is D Spermatogonia $\to$ Primary spermatocytes $\to$ Secondary spermatocytes $\to$ Spermatids $\to$ Sperms

Spermatogenesis is the process of formation of spermatid(n) from spermatogonia$\left(2n\right)$. The process goes as follows:-

Spermatogonia$\left(2n\right)⟶$ Primary Spermatocyte$\left(2n\right)⟶$Secondary Spermatocyte$\left(n\right)⟶$ Spermatid$\left(n\right)⟶$ Sperms$\left(n\right)$

Spermiogenesis is the metamorphosis of spermatid into sperm.

So the correct answer is D.
