The number of spermatids produced from primary spermatocytes is?
Correct answer: D. 4
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
Each primary spermatocyte undergoes two rounds of meiotic division, known as meiosis I and meiosis II. The result of these divisions is four haploid spermatids. This entire process is called spermatogenesis, which ultimately results in the formation of four mature sperm cells. Option A is incorrect as only one spermatid is not produced; Option B is incorrect because two spermatids are not the final result; Option C is incorrect as three spermatids are not produced in this process.
