One of the following is not related to mutation Theory

Options

A. Continuous variation
B. Hugo de Vries
C. Oenothera Lamarckian
D. Inheritable character of mutations

Answer

To determine which option is not related to mutation theory, we need to understand the key concepts of mutation theory as proposed by Hugo de Vries. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand Mutation Theory
Mutation theory, introduced by Hugo de Vries, posits that mutations are sudden, discontinuous changes in organisms that can lead to new traits. These changes can occur in the germ cells (which are inherited) and can also happen in somatic cells (which are not inherited).

**Hint:** Recall that mutation theory emphasizes sudden changes rather than gradual changes.

### Step 2: Identify Key Characteristics of Mutation
- **Discontinuous Variation:** Mutations lead to sudden changes in traits rather than gradual changes.
- **Heritability:** Only mutations occurring in germ cells can be inherited.
- **Jerky Changes:** The changes are unexpected and can result in new forms or traits.

**Hint:** Focus on the difference between continuous and discontinuous variation.

### Step 3: Analyze the Options
The question asks for the option that is not related to mutation theory. Based on the principles of mutation theory:
- **Continuous Variation:** This refers to gradual changes that occur over time, which is contrary to the concept of mutation theory.

**Hint:** Continuous variation is associated with gradual changes in traits, which does not align with the concept of sudden mutations.

### Step 4: Conclusion
The option that is not related to mutation theory is **continuous variation**. This is because mutation theory emphasizes discontinuous changes rather than gradual ones.

**Final Answer:** Continuous variation is not related to mutation theory.
