Duchenne muscular dystrophy is a sex-linked disorder. If a father has a normal X chromosome and the mother is a carrier:

1. What are the odds that a male child would have Duchenne muscular dystrophy?
2. What are the odds for a female child to have the disease or be a carrier?

The chance would be 50/50... because the father doesn't have that gene (50) and the mother has that gene (50) or half and half... hope that answered your question

A male child has a 50% chance of having Duchenne muscular dystrophy if his mother is a carrier. A female child has a 0% chance of having the disease but a 50% chance of being a carrier. This is due to the X-linked recessive inheritance pattern of the disorder.
