The example of cutting tails of mice is useful for explaining which idea?
Answer and explanation
Correct answer: Acquired traits are usually not inherited
The governing concept is that a body modification is not automatically a hereditary change. Cutting a mouse’s tail alters a somatic body part, but it does not normally alter the genetic information carried by its reproductive cells. If tailless mice are bred, their offspring are generally born with tails, showing that the acquired loss was not inherited. Option A is correct; B and C contradict heredity, and D is false.
