Sometimes in yeast the conjugation takes place between a parent cell and a bud . It is

Options

A. Isogamy
B. Pedogamy
C. Pseudogamy
D. Syngamy

Explanation

To answer the question regarding the type of conjugation that occurs between a parent yeast cell and a bud, we can analyze the options provided:

1. **Understand the terms**:
- **Isogamy**: This refers to a type of sexual reproduction where the gametes involved are of similar size and shape.
- **Pedogamy**: This is a form of reproduction where a mother cell and a daughter cell (bud) fuse to form a zygote.
- **Pseudogamy**: This is a process where fertilization occurs without the actual fusion of gametes; typically, it involves the stimulation of an egg cell by sperm without the sperm contributing genetic material.
- **Syngamy**: This is the process where two gametes fuse to form a zygote, leading to sexual reproduction.

2. **Analyze the question**:
- The question specifies that conjugation occurs between a parent cell and a bud in yeast. This indicates a fusion between a mother cell and its offspring (bud).

3. **Identify the correct option**:
- Given the definitions, the process that best describes the fusion between a parent cell and a bud is **pedogamy**, as it specifically involves the fusion of a mother cell with its daughter cell (bud) to produce a zygote.

4. **Conclusion**:
- Therefore, the correct answer to the question is **pedogamy**.

### Summary:
The type of conjugation that occurs between a parent yeast cell and a bud is **pedogamy**.
