Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Primary spermatocytes
Concept:

Spermatogenesis follows a strict sequence of mitotic and meiotic cell state changes.

Solution:

  • Spermatogonia are diploid stem cells located at the basement membrane of the seminiferous tubule.


  • When a Type B spermatogonium commits to differentiation, it undergoes a period of growth and enlarges.


  • This direct morphological change, prior to any meiotic division, transforms it into a diploid primary spermatocyte.


Why other options are incorrect:

Secondary spermatocytes are formed after the primary spermatocyte completes Meiosis I. Spermatids and sperms appear even later in the pathway.

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.
