Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Primary oocyte
Concept:

Oogenesis utilizes highly unequal cytokinesis to preserve cytoplasm for the viable ovum.

Solution:

  • A diploid primary oocyte undergoes Meiosis I.


  • To ensure the resulting egg has enough nutrients and machinery to support an early embryo, the cell divides its cytoplasm highly unequally.


  • It produces one large secondary oocyte and one tiny, non-functional cell consisting mostly of genetic waste, called the first polar body.


Why other options are incorrect:

The secondary oocyte undergoes Meiosis II to produce the second polar body. Oogonia only undergo mitosis to become primary oocytes.

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.
