The incorrect statement with regard to Haemophilia is :

  1. It is a recessive disease
  2. It is a dominant disease
  3. A single protein involved in the clotting of blood is affected
  4. It is a sex-linked disease

Correct answer: It is a dominant disease

Solution

Haemophilia is typically an X-linked recessive disorder, so it is not dominant. It involves a defect in a clotting factor protein and is sex-linked, which matches the other correct statements.
