Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Haploid plants
Concept:

Androgenesis and haploid plant generation.

Solution:

Culturing immature anthers containing haploid microspores (pollen grains) stimulates development into haploid plants (\( n \)), which can be doubled with colchicine to form homozygous diploids.

Why other options are incorrect:

  • Triploid fruits: Generated by crossing tetraploid and diploid parents (e.g., seedless watermelons), not anther culture.


  • Tetraploid roots: Produced by chromosome doubling chemicals or polyploidy breeding techniques.


  • Diploid seeds: Formed naturally through standard double fertilization events in angiosperms.

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.
