Assertion: Vegetative propagation is a type of asexual reproduction.
Reason: The formation of vegetative propagagules does not involve two parents.

Explanation

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Vegetative propagation is a type of asexual reproduction." To evaluate this, we need to define both terms.

2. **Definition of Asexual Reproduction**: Asexual reproduction is a mode of reproduction that involves only one parent and results in offspring that are genetically identical to the parent. This means that the offspring are clones of the parent organism.

3. **Definition of Vegetative Propagation**: Vegetative propagation is a form of asexual reproduction in plants where new individuals are produced from vegetative parts of the plant, such as roots, stems, or leaves, rather than from seeds.

4. **Evaluating the Assertion**: Since vegetative propagation involves only one parent (the original plant) and produces genetically identical offspring, it fits the definition of asexual reproduction. Therefore, the assertion is true.

5. **Understanding the Reason**: The reason states that "The formation of vegetative propagules does not involve two parents." This aligns with the definition of asexual reproduction, where only one parent is involved.

6. **Evaluating the Reason**: Since vegetative propagation indeed does not involve two parents and is characterized by the production of offspring from a single parent, the reason provided is also true.

7. **Conclusion**: Both the assertion and the reason are true, and the reason correctly explains the assertion.

### Final Answer:
- **Assertion**: True
- **Reason**: True
- **Conclusion**: Both the assertion and the reason are true, and the reason supports the assertion.
