Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Artificial selection
Concept:

Selection pressure can be exerted either by environmental factors or by intentional human intervention.

Solution:

  • When humans act as the selective agent—choosing specific plants or animals with desirable traits to reproduce—the process is called Artificial selection.
  • This method has been used for millennia to create modern agricultural crops, livestock breeds, and dog breeds from wild ancestors.


Why other options are incorrect:

  • Natural selection: The environment dictates survival and reproductive success, not human preference.
  • Genetic drift: A random fluctuation in allele frequencies, not a purposeful selection.

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.
