The reappearance of the hidden dwarf trait in the second generation disproves which idea?
Answer and explanation
Correct answer: Traits blend completely and disappear
The governing concept is the particulate, or discrete-unit, view of inheritance. If tall and dwarf traits blended completely into a permanent intermediate substance, the dwarf trait could not return unchanged in the second generation. Its reappearance shows that hereditary factors remain distinct, with the recessive factor hidden in the first generation. Therefore option A is the idea disproved by the observation.
