Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Tritanopia
Concept:

Color blindness is classified by which specific cone cells (red, green, or blue) in the retina are defective or absent.

Solution:

  • Tritanopia is a rare, autosomal genetic condition characterized by a severe defect or absence of the short-wavelength (blue) cone cells in the retina.
  • Consequently, it is commonly known as blue color blindness, impairing the ability to distinguish between blue and yellow shades.


Why other options are incorrect:

  • Protanopia: Severe red color blindness (defective L-cones).
  • Deuteranopia: Severe green color blindness (defective M-cones).

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.
