Assertion :- Autopolypoids have more than two copies of a single genome.
Reason : Alloplypoids contain more than one type of genome each with atleast two copies.

Options

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

Answer

To analyze the given assertion and reason, we will break down the definitions and characteristics of autopolypoids and allopolypoids step by step.

### Step-by-Step Solution:

1. **Understanding Autopolyploids**:
- **Definition**: Autopolyploids are organisms that have more than two sets of chromosomes derived from the same species.
- **Key Point**: They have multiple copies of a single genome, which means that all chromosome sets are identical and come from one species.

2. **Understanding Allopolyploids**:
- **Definition**: Allopolyploids are organisms that have more than two sets of chromosomes, but these sets come from different species.
- **Key Point**: They contain more than one type of genome, with each type having at least two copies. This means that the genetic material is a combination of genomes from different species.

3. **Evaluating the Assertion**:
- The assertion states: "Autopolyploids have more than two copies of a single genome."
- Based on our understanding, this statement is **true** because autopolyploids do indeed have multiple copies of the same genome.

4. **Evaluating the Reason**:
- The reason states: "Allopolyploids contain more than one type of genome, each with at least two copies."
- This statement is also **true** as allopolyploids consist of different genomes, each present in multiple copies.

5. **Conclusion**:
- Both the assertion and the reason are true statements.
- However, the reason does not correctly explain the assertion because the nature of the genomes in autopolyploids and allopolyploids is fundamentally different.

### Final Answer:
- The answer is **B**: Both the assertion and reason are true, but the reason is not the correct explanation for the assertion.
