🧠 Explanation:

Haemophilia, a hereditary disease, impairs blood clotting, leading to excessive bleeding from minor injuries. Caused by genetic mutations affecting clotting factors, it’s passed through families, primarily affecting males. Symptoms include prolonged bleeding and bruising, requiring treatments like factor replacement therapy. Its hereditary nature makes genetic counseling vital. Haemophilia’s study advances medical understanding of blood disorders, improving patient care. Its management highlights the importance of genetic research and specialized treatments, ensuring better quality of life for those affected. The disease’s impact underscores the need for ongoing medical innovation in hereditary conditions.
