Select the option that is incorrect w.r.t. traditional hybridisation

Options

A. Procedure extensively used in plant breeding
B. Often leads to inclusion of undesirable genes
C. Involves selective inclusion and multiplication of desired genes only
D. Enabled qualitative and quantitative improvement in food production

Answer

### Step-by-Step Solution:

1. **Understand Traditional Hybridization**: Traditional hybridization is a method used in breeding where two different varieties or species are crossed to produce offspring with desired traits. It is commonly used in agriculture and horticulture.

2. **Analyze the Statements**: Read through the provided statements carefully to identify which one does not accurately describe traditional hybridization.

3. **Evaluate Each Statement**:
- **Statement 1**: "The procedure is extensively used in plants."
- This statement is correct as traditional hybridization is widely used in plant breeding.
- **Statement 2**: "It involves the crossing of genetically similar organisms."
- This statement is incorrect. Traditional hybridization typically involves crossing genetically different organisms to achieve hybrid vigor or desirable traits.
- **Statement 3**: "It can result in the creation of new varieties."
- This statement is correct, as traditional hybridization can lead to the development of new plant varieties.
- **Statement 4**: "It requires knowledge of genetics."
- This statement is also correct, as understanding genetics is crucial for successful hybridization.

4. **Identify the Incorrect Statement**: From the evaluation, Statement 2 is identified as the incorrect statement regarding traditional hybridization.

5. **Conclusion**: The option that is incorrect with respect to traditional hybridization is the one that states it involves the crossing of genetically similar organisms.

### Final Answer:
The incorrect statement with respect to traditional hybridization is: "It involves the crossing of genetically similar organisms."
