Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Monkey
Concept:

The nomenclature of genetic discoveries often reflects the original organism in which they were found.

Solution:

  • The Rh blood group is one of the most complex blood group systems in humans.
  • It was discovered approximately 60 years ago by Karl Landsteiner and Alexander S. Wiener.
  • It was first studied and identified in the blood of the Rhesus monkey, which is why it was named the 'Rh' factor.


Why other options are incorrect:

  • While it is heavily studied in man, its initial discovery and naming origin belong specifically to the Rhesus macaque monkey.

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.
