Which of the following statements are true for spermatogenesis but do not hold true for Oogenesis ?

(a) It results in the formation of haploid gametes

(b) Differentiation of gamete occurs after the completion of meiosis

(c) Meiosis occurs continuously in a mitotically dividing stem cell population

(d) It is controlled by the Luteinising hormone (LH) and Follicle Stimulating Hormone (FSH) secreted by the anterior pituitary

(e) It is initiated at puberty

Choose the most appropriate answer from the options given below :

1. (b), (c) and (e) only

2. (c) and (e) only

3. (b) and (c) only

4. (b), (d) and (e) only

1 answer

Best answer

Answer: 1. (b), (c) and (e) only

Key idea: Compare each statement for the two processes.

  • (a) Both give haploid gametes. Not exclusive.
  • (b) In spermatogenesis, spermatids differentiate into sperms (spermiogenesis) after meiosis. In oogenesis the egg is not formed by such differentiation. Exclusive to spermatogenesis.
  • (c) Spermatogonia keep dividing by mitosis and feed meiosis continuously. Oogonia stop dividing before birth. Exclusive.
  • (d) Both are controlled by LH and FSH. Not exclusive.
  • (e) Spermatogenesis starts at puberty, whereas oogenesis starts in the embryo. Exclusive.

So (b), (c) and (e) only: option 1.
