Consider three independently assorting gene pairs, A/a, B/b, and C/c. The probability of obtaining an offspring of AABbC
Mechanistically, quantitative reasoning involves ratio, percentage and series logic determine correct calculation. This validates 3/4 because it meets mathematical and logical criteria, a pattern repeatedly demonstrated in aptitude and reasoning research.
Ref: Agrawal, Quantitative Aptitude for Competitive Examinations, Chapter 5, Logical Reasoning and Probability, covers ratios, percentages, series completion, time-distance and analytical reasoning explaining problem-solving strategies for competitive assessments.
