Weismann's experiment weakened which idea?
Answer and explanation
Correct answer: Inheritance of acquired traits
The governing concept is the distinction between inherited genetic information and changes acquired by body parts. Weismann removed the tails of mice over several generations, yet their offspring continued to develop normal tails. This observation weakened the claim that an acquired bodily change is automatically inherited. Therefore, option A is correct. The experiment did not disprove chromosomes, dominance, or variation in sexual reproduction.
