Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Seven pairs
Concept:

Mendel's success was largely due to his careful selection of distinct, easily distinguishable traits.

Solution:

  • Mendel meticulously selected and studied seven pairs of contrasting traits in pea plants.
  • These included: Seed shape (Round/Wrinkled), Seed color (Yellow/Green), Flower position (Axial/Terminal), Flower color (Violet/White), Pod shape (Inflated/Constricted), Pod color (Green/Yellow), and Stem height (Tall/Dwarf).


Why other options are incorrect:

  • While he studied inheritance one or two traits at a time (monohybrid/dihybrid crosses), his overarching foundational research was based on exactly seven distinct pairs of characters.

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.
