Problem:
1. Hemophilia is caused by an X-linked recessive gene. The condition results in slower than normal blood clotting time. Sue has normal clotting time, but her father has hemophilia. John has normal clotting time. John and Sue have a son and a daughter.
Required:
Question 1: What is the chance the daughter is a carrier?
Question 2: What is the chance the son has hemophilia?
2. John and Sue later have another son, Bill. Bill has hemophilia. He marries Donna. Donna has normal clotting time, but her father also has hemophilia. (seems to be a lot of that going around) They also have a son and a daughter. Be careful again.
Required:
Question 1: What is the chance the daughter has hemophilia?
Question 2: What is the chance the son has hemophilia?
Please Explain don't just write the answer.
