Q65 / 200 · MHT CET - Medical 2026 (25 April Shift 1) · Biology
How many spermatozoa will be formed from 100 primary spermatocytes?
- A$200$
- Correct answerB$400$
- C$600$
- D$800$
Solution
One primary spermatocyte undergoes meiosis I to produce two secondary spermatocytes.
Each secondary spermatocyte undergoes meiosis II to produce two spermatids.
Thus, a single primary spermatocyte produces four spermatids.
Each spermatid differentiates into one spermatozoon through spermiogenesis.
Therefore, one primary spermatocyte yields four spermatozoa.
For $100$ primary spermatocytes, the number of spermatozoa formed is $100 \times 4 = 400$.
