Detailed explanation-1: -Hemophilia is usually an inherited bleeding disorder in which the blood does not clot properly. This can lead to spontaneous bleeding as well as bleeding following injuries or surgery. Blood contains many proteins called clotting factors that can help to stop bleeding.
Detailed explanation-2: -Hemophilia A is a hereditary bleeding disorder caused by a lack of blood clotting factor VIII. Without enough factor VIII, the blood cannot clot properly to control bleeding.
Detailed explanation-3: -Hemophilia is caused by the lack of clotting factor VIII or IX in the blood. In most cases, hemophilia is passed down through families (inherited). Most of the time, it is passed to male children.
Detailed explanation-4: -Hemophilia is an inherited disease, most commonly affecting males, that is characterized by a deficiency in blood clotting. The responsible gene is located on the X chromosome, and since males inherit only one copy of the X chromosome, if that chromosome carries the mutated gene then they will have the disease.
Detailed explanation-5: -Haemophilia is a disorder in which blood clotting factors (factor VII or IX) are not produced sufficiently and hence the blood fails to clot. As a result there is easy bruising and blood clotting does not occur after an injury. It is a sex linked recessive disorder.
