Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Primary spermatocytes
Concept:

The progression of spermatogenesis moves from diploid stem cells to haploid gametes through specific developmental stages.

Solution:

  • Type B spermatogonia (diploid cells) undergo a period of growth and differentiation.


  • They enlarge and prepare for the first meiotic division, directly becoming diploid primary spermatocytes.


Why other options are incorrect:

Primary spermatocytes must undergo Meiosis I to become secondary spermatocytes. Secondary spermatocytes undergo Meiosis II to become spermatids, which then differentiate into spermatozoa. Spermatogonia do not jump straight to these later stages.

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.
