Answer

To solve the question regarding the number of parents involved in asexual and sexual reproduction, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Asexual Reproduction**:
- Asexual reproduction involves only **one parent**.
- The offspring produced are genetically identical to the parent.
- Examples include budding, binary fission, and vegetative propagation.

2. **Understanding Sexual Reproduction**:
- Sexual reproduction involves **two parents**.
- It combines genetic material from both a male and a female.
- This process includes the formation of gametes (sperm and egg), which fuse during fertilization to form a zygote.
- Examples include reproduction in humans, cats, and dogs.

3. **Identifying the Number of Parents**:
- For asexual reproduction: **1 parent**.
- For sexual reproduction: **2 parents**.

4. **Conclusion**:
- The number of parents involved in asexual reproduction is **1**.
- The number of parents involved in sexual reproduction is **2**.

### Final Answer:
- The number of parents involved in asexual reproduction is **1** and in sexual reproduction is **2**.
