A man's who suffers from haemophilia marries a woman who is a carrier, what percentage of their children are likely to be haemophilie?
Answer Details
Haemophilia is a genetic disorder that is passed down from parent to child through their genes. It is a recessive disorder, which means that an individual must inherit two copies of the defective gene (one from each parent) in order to have the disorder.
In this case, the man has haemophilia, which means he has two copies of the defective gene. The woman is a carrier, which means she has one normal gene and one defective gene. When they have children, each child has a 50% chance of inheriting the defective gene from their mother and a 50% chance of inheriting the defective gene from their father.
Therefore, the probability of their children having haemophilia is 50%.
