Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Artificial selection
Concept:

Evolutionary mechanisms can be steered by human intent.

Solution:

  • Artificial selection (or selective breeding) occurs when humans purposefully act as the selective pressure.
  • By deliberately breeding individuals that possess favorable traits (e.g., higher milk yield in cows, larger kernels in corn), humans accelerate and direct evolutionary changes within a population over relatively few generations.


Why other options are incorrect:

  • Natural selection: Selection is driven entirely by natural environmental factors, without any purposeful intent.
  • Genetic drift: A totally random change in allele frequencies due to chance events, unrelated to 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.
