Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Alleles
Concept:

Gregor Mendel established the fundamental laws of inheritance. He postulated that hereditary traits are passed down by discrete factors.

Solution:

  • Mendel originally termed these discrete units of inheritance as Elementen.
  • In modern genetics, these two hereditary factors for each trait are now called Alleles (or genes).
  • Therefore, the correct answer for what they are now called is Alleles (Option B).


Why other options are incorrect:

  • Option D (Elementen): This was Mendel's original 19th-century terminology, not what they are now called.
  • Options A & C (Chromatids / Chromosomes): Structural nuclear structures containing DNA, not the specific term for the paired hereditary factors for a trait.

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.
