Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Spermatids
Concept:

Maturation of sperm involves extensive morphological remodeling of already haploid cells.

Solution:

  • At the end of Meiosis II, haploid cells called spermatids are formed.


  • These spermatids are round and non-motile. They undergo a morphological transformation known as spermiogenesis (shedding excess cytoplasm, forming a tail) to eventually mature into spermatozoa.


Why other options are incorrect:

Spermatogonia and primary spermatocytes are diploid. Secondary spermatocytes are haploid but must first undergo Meiosis II to become spermatids before structural maturation can occur.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
