In gametogenesis, which resultant product is non-functional?
Correct answer: C. C. Polar body
- A. A. Spermatogonia
- B. B. Oogonia
- C. C. Polar body
- D. D. Ovum
Explanation
The correct answer is Option C: Polar body. During oogenesis, a mature ovum is formed alongside smaller cells known as polar bodies. Polar bodies are haploid cells that lack the cytoplasmic components necessary for fertilization, rendering them non-functional in terms of reproductive capability. On the other hand, spermatogonia (Option A) and oogonia (Option B) are precursor cells that eventually lead to the production of functional gametes. The ovum (Option D) is the egg cell capable of being fertilized, making it the functional product of oogenesis.

About Reproduction
Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
