Final answer:
The likelihood of having a girl with hemophilia is 0% and the likelihood of having a boy with hemophilia is 50%.
Step-by-step explanation:
The likelihood of a couple having a girl with hemophilia is 0%, while the likelihood of having a boy with hemophilia is 50%.
In this scenario, the female is a carrier for hemophilia, which means she has one normal X chromosome and one X chromosome with the hemophilia gene. The male, on the other hand, does not have hemophilia and has one normal X chromosome and one Y chromosome.
Since hemophilia is a recessive X-linked disorder, a girl would need to inherit two affected X chromosomes, one from each parent, to have hemophilia. However, in this case, the female only has one affected X chromosome, so the likelihood of having a girl with hemophilia is 0%. On the other hand, a boy only needs to inherit one affected X chromosome from his mother, which is the case here, so the likelihood of having a boy with hemophilia is 50%.
