Question

The view of inheritance of acquired characters of Lamarck was opposed by

• A. Spencer
• B. Kammarer
• C. Weismann
• D. Hugo de Vries

Hint:

Remember: \[ \boxed{ \begin{aligned} &\text{Lamarck} &&\rightarrow \text{Inheritance of acquired characters} &\text{Weismann} &&\rightarrow \text{Opposed Lamarck by germplasm theory} \end{aligned} } \]

Answer 1

The Correct Option is C

Step 1: Recall Lamarck's theory. Lamarck proposed the theory of inheritance of acquired characters, according to which traits acquired during an organism's lifetime are transmitted to its offspring.

Step 2: Recall Weismann's experiment. August Weismann disproved this idea through his tail-cutting experiment on mice. Despite removing the tails of mice for many generations, all offspring were born with normal tails. This led to the germplasm theory, which states that acquired characters are not inherited.

Step 3: Choose the correct option. Hence, \[ \boxed{(C)} \] is the correct answer.
