Official Correct Choice:
Option D: Hardy Weinberg
Concept:

Population genetics relies on mathematical models to determine if an evolving population is stable (in equilibrium).

Formula:

$$p^2 + 2pq + q^2 = 1$$

Solution:

  • G.H. Hardy (a mathematician) and Wilhelm Weinberg (a physician) independently derived this principle in 1908.
  • The Hardy-Weinberg equation allows scientists to calculate expected allele and genotype frequencies in a stable, non-evolving population under ideal conditions.


Why other options are incorrect:

  • Darwin/Lamarck/Linnaeus: These prominent early biologists did not develop the mathematical foundations of population genetics; their work preceded the integration of genetics and evolution (the Modern Synthesis).

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.
