Assertion: The techniques of genetic engineering allow us to isolate & introduce only desired genes without introducing undesirable genes
Reason :Traditional hybridization procedure lead to inclusion of undesirable genes along with desirable genes

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion
B. It both Assertion & Reason are True but Reason is not a correct explanation of the Assetion
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are false

Answer

To solve the question regarding the assertion and reason statements, we will analyze both statements step by step.

### Step 1: Understand the Assertion
The assertion states that "The techniques of genetic engineering allow us to isolate & introduce only desired genes without introducing undesirable genes."

- **Explanation**: Genetic engineering techniques, such as recombinant DNA technology, utilize tools like restriction enzymes (often referred to as molecular scissors) to cut specific segments of DNA. This allows scientists to isolate only the genes of interest (desired genes) and insert them into vectors for further use, without the risk of incorporating unwanted genes.

### Step 2: Understand the Reason
The reason states that "Traditional hybridization procedures lead to inclusion of undesirable genes along with desirable genes."

- **Explanation**: Traditional hybridization involves crossing two organisms to produce offspring. This method does not allow for the precise selection of genes; thus, both desirable and undesirable genes are inherited together. This can lead to the introduction of traits that may be harmful or not beneficial in the offspring.

### Step 3: Analyze the Relationship Between Assertion and Reason
Now, we need to determine if both statements are true and if the reason correctly explains the assertion.

- **Truth of Assertion**: The assertion is true because genetic engineering indeed allows for the isolation of specific genes.
- **Truth of Reason**: The reason is also true as traditional hybridization does not allow for the selective introduction of only desirable genes.
- **Correct Explanation**: The reason correctly explains why genetic engineering is preferred over traditional hybridization for isolating and introducing specific genes.

### Conclusion
Both the assertion and the reason are true, and the reason provides a correct explanation for the assertion. Therefore, the answer to the question is that both statements are true, and the reason is the correct explanation of the assertion.

### Final Answer
Both the assertion and the reason are true, and the reason is a correct explanation of the assertion.
