Question:
In the process of spermatogenesis, the second meiotic division forms
In the process of spermatogenesis, the second meiotic division forms
Show Hint
To remember the divisions easily:
- Primary Spermatocyte $\xrightarrow{\text{Meiosis I}}$ Secondary Spermatocytes
- Secondary Spermatocytes $\xrightarrow{\text{Meiosis II}}$ Spermatids
- Primary Spermatocyte $\xrightarrow{\text{Meiosis I}}$ Secondary Spermatocytes
- Secondary Spermatocytes $\xrightarrow{\text{Meiosis II}}$ Spermatids
Updated On: Aug 24, 2026
- Spermatogonia
- Primary spermatocyte
- Secondary spermatocyte
- Spermatids

The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Spermatogenesis is the process by which male germ cells develop into mature spermatozoa within the seminiferous tubules of the testes.
This process involves mitotic division, followed by two successive meiotic divisions.
Step 2: Detailed Explanation:
Let us review the sequential stages of spermatogenesis:
1. Spermatogonia (diploid stem cells) undergo mitotic divisions to maintain their population and differentiate into primary spermatocytes.
2. Primary spermatocytes undergo the first meiotic division (Meiosis I), which is a reduction division, to form haploid secondary spermatocytes.
3. Secondary spermatocytes immediately enter the second meiotic division (Meiosis II), which is an equational division, to form haploid spermatids.
4. Spermatids then undergo a non-divisive morphogenetic transformation called spermiogenesis to become mature spermatozoa.
Therefore, the second meiotic division directly forms spermatids.
Step 3: Final Answer
The correct option is (D).
