You must try to answer both questions: Cystic fibrosis (CF) is an inherited disorder that causes severe damage to the lungs, the digestive system and other organs within the body. CF affects cells that produce thin and slippery mucus and cause the secretions to become sticky and thick. CF is caused by a deletion mutation on chromosome 7. In order for a child to have cystic fibrosis they must inherit a defective gene from each of his/her parents a) Rob...
