Answer 2

Answer:

The answer is B. By studying the family’s pedigree chart

Explanation:

Cystic fibrosis is an inherited disorder that tends to be fatal, since it damages the lungs and digestive system. Cystic fibrosis affects the cells that produce mucosa, sweat and gastric juices, causing them to become thick and sticky, causing the tubes, tracts and channels to become clogged. It is a hereditary disease, caused by a defective gene (so the best way to predict it would be through studying the family's pedigree chart) that leads the body to produce an abnormally thick and sticky fluid.
