What is the pattern of inheritance of haemophilia A?

Question

Quizplus · Accepted Answer

Haemophilia A is inherited in an X-linked recessive pattern, where the mutation is present on the X chromosome. Females have two X chromosomes, and males have one X chromosome and one Y chromosome. Therefore, males are much more likely to develop haemophilia A as they have only one copy of the X chromosome, and if the X chromosome carries the mutation, they will have the condition. Females can be carriers of the condition, but they are usually not affected as they have a functional copy of the X chromosome.
