NEET 2022 Zoology Oogenesis MCQ Question
Which of the following statements are true for spermatogenesis but do not hold true for Oogenesis?
i. It results in the formation of haploid gametes
ii. Differentiation of gamete occurs after the completion of meiosis
iii. Meiosis occurs continuously in a mitotically dividing stem cell population
iv. It is controlled by the Luteinising hormone (LH) and Follicle Stimulating Hormone (FSH) secreted by the anterior pituitary
v. It is initiated at puberty
Choose the most appropriate answer from the options given below:
ii, iv and v only
ii, iii and v only
iii and v only
ii and iii only
Correct Answer
Detailed Explanation
Chapter: Human Reproduction
Class: 12 | Topic: Spermatogenesis vs Oogenesis | Difficulty: π΄ Hard
β Ans: B β ii, iii and v only
- i β Both form haploid gametes.
- ii β In spermatogenesis, spermatids differentiate into sperm after meiosis (spermiogenesis).
- iii β Spermatogenesis continues from a mitotically dividing spermatogonial stem-cell population; oogenesis does not continue this way after birth. (Quantrex Academy)
- iv β Both are regulated by LH and FSH.
- v β Spermatogenesis begins at puberty, whereas oogenesis begins during embryonic development. (medicneet.com)
π NCERT: Spermatogenesis begins at puberty and involves continuous production from spermatogonia; oogenesis begins during embryonic development.
π§ Quick Revision: Spermatogenesis only β After-meiosis differentiation + Continuous meiosis + Starts at puberty
So your marked B is correct.
