From the description of cystic fibrosis above, which of the following statements is correct? Correct Answer Cystic fibrosis is an example of pleiotropy because one mutated gene causes multiple effects.

(C) Cystic fibrosis is solely an inherited disease. No environmental component causes the disease. It is an autosomal recessive disease. In order to have the disease, a person must have inherited two mutated genes, one from each parent. Polygenic inheritance involves the inheritance of several genes. An example is height, skin, or hair color—any trait where a tremendous variety occurs in a population.
