Question

How can a female be haemophilic?

• A. Mother is haemophilic and father is normal
• B. Mother is a carrier and father is haemophilic
• C. Both mother and father are carriers
• D. Both mother and father are haemophilic

Answer 1

Answer:

B. Mother is a carrier and father is haemophilic

A female can only be haemophilic if her mother is at least a carrier of this disease and her father is haemophilic. But the possibility of a female becoming haemophilic is extremely rare because being haemophilic for the parents at the later stage of life is unviable.
