Which is not related with the sexual reproduction in protozoans

Options

A. Cytogamy
B. Schizogony
C. Autogamy
D. Conjugation.

Explanation

To determine which option is not related to sexual reproduction in protozoans, we need to analyze each of the given terms: cytogamy, schizogony, autogamy, and conjugation.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Cytogamy**: This is a form of sexual reproduction in which two protozoan cells fuse together to form a zygote.
- **Schizogony**: This is a method of asexual reproduction where a single organism divides multiple times to produce several daughter cells. It involves multiple fission and does not involve the fusion of gametes.
- **Autogamy**: This is a form of sexual reproduction where an organism fertilizes itself, leading to the formation of a zygote.
- **Conjugation**: This is a process where two protozoans exchange genetic material, leading to genetic variation and is considered a form of sexual reproduction.

2. **Identifying the Asexual Process**:
- From the definitions, we can see that cytogamy, autogamy, and conjugation are all related to sexual reproduction as they involve the fusion of gametes or genetic exchange.
- Schizogony, on the other hand, is strictly an asexual process.

3. **Conclusion**:
- Therefore, the option that is not related to sexual reproduction in protozoans is **schizogony**.

### Final Answer:
**Schizogony is not related to sexual reproduction in protozoans.**
