Answer

To answer the question of how many ova are released in the case of maternal twins and fraternal twins respectively in humans, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Understanding Maternal Twins**:
- Maternal twins, also known as identical or monozygotic twins, develop from a single fertilized egg (zygote).
- In this case, only **one ovum (egg)** is released from the ovary during ovulation.

2. **Understanding Fraternal Twins**:
- Fraternal twins, also known as dizygotic twins, develop from two separate fertilized eggs.
- This means that during ovulation, **two ova (eggs)** are released and each is fertilized by a different sperm.

3. **Conclusion**:
- Therefore, in the case of maternal twins, **1 ovum** is released, and in the case of fraternal twins, **2 ova** are released.

### Final Answer:
- Maternal twins: 1 ovum
- Fraternal twins: 2 ova
