Answer

To answer the question "During copulation, cockroach transfers male gametes in the form of -", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Copulation in Cockroaches**:
- Copulation refers to the mating process where male and female organisms come together for reproduction.

2. **Identifying Male Gametes**:
- Male gametes in cockroaches are the sperm cells, which are necessary for fertilization.

3. **Form of Male Gametes Transfer**:
- In cockroaches, male gametes are transferred in the form of **spermatophores**. A spermatophore is a capsule or mass that contains sperm.

4. **Mechanism of Transfer**:
- During copulation, the male cockroach transfers the spermatophore into the female's body. This process is known as internal fertilization.

5. **Fertilization Process**:
- Once inside the female's body, the sperm in the spermatophore fertilizes the ovum (egg). The fertilization is internal, but the eggs are produced externally.

6. **Conclusion**:
- Therefore, the correct answer is that during copulation, cockroaches transfer male gametes in the form of **spermatophores**.

### Final Answer:
During copulation, cockroach transfers male gametes in the form of **spermatophores**.
