Hemophilia A is a genetic deficiency of the factor VIII protein involved in blood clotting. This disorder is more common in males becauseMultiple choice question.the affected gene is on the Y chromosome.only males have this blood clotting protein.only females have this blood clotting protein.the affected gene is on the X chromosome.
Solution
The correct answer is: the affected gene is on the X chromosome.
Here's why:
Hemophilia A is a genetic disorder caused by a deficiency of the factor VIII protein, which is involved in blood clotting. The gene responsible for this protein is located on the X chromosome.
Males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). If a male inherits an X chromosome with the affected gene, he will have Hemophilia A because he doesn't have a second X chromosome to compensate for the defect.
On the other hand, females who inherit one affected X chromosome usually don't show symptoms of the disease because they have a second, normal X chromosome. They are typically carriers of the disease and can pass it on to their children.
Therefore, Hemophilia A is more common in males because the affected gene is on the X chromosome.
