Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Sperm cell
Concept:

Gametes are reproductive cells produced by meiosis, containing half the genetic material of somatic cells.

Solution:

  • A human sperm cell is a male gamete.


  • Because it is produced via reductional division (meiosis), it contains a single set of chromosomes, making it haploid (\(n\)).


  • Upon fertilization with a haploid egg, the normal diploid (\(2n\)) number is restored in the zygote.


Why other options are incorrect:

Skin cells, muscular cells, and mesophyll cells (in plants) are all somatic (body) cells that undergo mitosis and remain diploid (\(2n\)).

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.
