17. You are a genetic counselor, and it is your job to predict the liklihood of certain couples having babies with genetic disorders. A woman named Nichole comes seeking your help because she has a family history of Duchenne Muscular Dystrophy, an X-linked, recessive genetic disorder. Nichole wants to have kids with her husband who has no family history of the disorder, but she is concerned that her child may be born with the disorder. Her father had muscular dystrophy. Nichole does not have muscular dystrophy, and her brother and sister also do not show the trait. Her brother has a healthy daughter and son. However, her sister has one son who suffers from muscular dystrophy, and one son who is healthy. Draw a complete pedigree of Nichole's family, and determin if it is possible for Nichole to pass the trait on to her offspring. If she can pass the trait, what is the probability that she will have a child with muscular dystrophy. What is the liklihood that she will have a child who is a carrier (a carrier can pass a trait to her offspring, but she does not exhibit the trait).
