What happens to a person suffering from hemophilia ?

Explanation

### Step-by-Step Solution:

1. **Definition of Hemophilia**: Hemophilia is a genetic disorder characterized by the deficiency or absence of certain clotting factors in the blood. This condition is primarily caused by mutations in genes located on the X chromosome.

2. **Clotting Factors**: Clotting factors are proteins in the blood that help control bleeding. In hemophilia, these factors are either absent or present in insufficient amounts, which impairs the blood's ability to clot properly.

3. **Symptoms of Hemophilia**:
