Official Correct Choice:
Option A: X-linked recessive disorder
Concept: X-linked recessive inheritance probabilities from a carrier mother.

Solution: A heterozygous carrier mother (\(X^H X^h\)) passes her mutated \(X^h\) allele to 50% of her offspring, resulting in a 50% chance of affected sons and a 50% chance of carrier daughters.

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.
