Homework Answers
Answere : The correct option is "pleiotropy".
Explanation : The inherited cystic fibrosis has several phenotypes, but is caused by a single gene with two alleles. Pleiotropy is the ability of a single gene to have multiple effects. In humans, pleiotropic alleles are responsible for multiple symptoms associated with certain hereditary diseases, such as cystic fibrosis and sickle-cell disease.

82 GENETICS LABORATORY MANUAL 4. Cystic fibrosis is one of the most common autosomal recessive diseases in people Northern European descent. A mutation in the CF gene affects a protein involved in the transport of chloride and sodium across cell membranes, causing thick mucus and secretions, lung damage, and nutritional deficiencies. The disease is inherited in an autosomal recessive manner, meaning one must inherit two mutated alleles in order to have the disease. Greg does not have cystic fibrosis, and...

5. (4) Upon graduating from university you land a job as a genetic counsellor. A couple comes to see you because each has a sibling with cystic fibrosis, although neither they nor their parents are affected. From your university training you know that cystic fibrosis is a recessive disorder that causes severe damage to the lungs, digestive system and other organs in the body.
