Question

What do you know about haemophilia?

Answer 1

Haemophilia is characterized by uncontrolled bleeding and the inability of the blood to clot properly. Even a small cut or a minor injury can result in severe bleeding. Haemophilia is one among the many X-linked recessive inherited genetic disorders, where the gene causing the disorder or dysfunction is located on the X-chromosome. For a female to be haemophilic, both X chromosomes should carry the defective gene. In males, only one copy of the X chromosome is present and it is sufficient for causing the disease. If the mother is a carrier of the disease then there are 50 per cent chances of the son being haemophilic.
