Question

Even if the tails of mice is cut off generation after generation, it neither disappears nor shortens in the next generation. This indicates that:

• A. Darwin's theory was incorrect
• B. Lamarck's theory was incorrect
• C. Mutation theory was incorrect
• D. (a) and (c) above.

Answer 1

The correct option is B Lamarck's theory was incorrect

Lamarck proposed a theory explaining the inheritance of acquired characters. It states that desirable characters an individual acquires in his/her lifetime are inherited by the next generations. Removing the tail of mice didn't alter the genetic composition and the acquired character didn't pass on to the next generation. This proved that Lamarck's theory was wrong.
