Assertion: A plant biotype can be retained and multiplied identifinitely without any change or variation by the method of asexual reproduction
Reason: Asexual reproduction does not involve meiosis and syngamy

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false
D. If both the assertion and reason is false

Answer

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

### Step 1: Analyze the Assertion
The assertion states: "A plant biotype can be retained and multiplied indefinitely without any change or variation by the method of asexual reproduction."

- Asexual reproduction involves processes such as binary fission, budding, or vegetative propagation, where new individuals are produced from a single parent without the involvement of gametes.
- Since asexual reproduction does not involve genetic recombination or variation, the offspring are genetically identical to the parent.
- Therefore, the assertion is **true** because a plant biotype can indeed be retained and multiplied indefinitely without any change or variation through asexual reproduction.

### Step 2: Analyze the Reason
The reason states: "Asexual reproduction does not involve meiosis and syngamy."

- Meiosis is the process that leads to the formation of gametes, which introduces genetic variation through recombination.
- Syngamy refers to the fusion of gametes, which also contributes to genetic diversity.
- Since asexual reproduction does not involve either meiosis or syngamy, it does not introduce genetic variation.
- Therefore, the reason is **true** because it accurately describes why asexual reproduction allows for the retention of the plant biotype without change.

### Step 3: Determine the Relationship
Now, we need to determine if the reason is a correct explanation of the assertion.

- The assertion is about the ability to retain and multiply a plant biotype without change through asexual reproduction.
- The reason explains that this lack of change is due to the absence of meiosis and syngamy in asexual reproduction.
- Since the reason provides a valid explanation for the assertion, we conclude that the reason is indeed a correct explanation of the assertion.

### Final Conclusion
Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, the correct option is:

**Option A: Both assertion and reason are true, and the reason is the correct explanation of the assertion.**
