Number of spermatozoa that a single primary spermatocyte ultimately produces in spermatogenesis is
Correct answer: B. Four
- A. One
- B. Four
- C. Two
- D. Eight
Explanation
A single primary spermatocyte ultimately produces 4 spermatozoa in spermatogenesis.This is because during spermatogenesis, a primary spermatocyte undergoes two meiotic divisions, resulting in four haploid spermatids. Each spermatid then undergoes a process called spermiogenesis, during which it matures into a spermatozoa. So option B is correct.
