Cystic fibrosis (CF) is a disorder caused by a random change in the gene that produces the cystic fibrosis transmembrane conductance regulator (CFTR) protein. In people with CF, random CFTR gene changes can disrupt the CFTR protein's normal production or function- ing. This protein is typically found in several organs, and as a result, the lungs, pancreas, di- gestive system, and other organs are affected. The symptoms of CF can range from breath- ing difficulties to recurrent infections. Which of the following best describes the effects of cystic fibrosis? A B с D Cystic fibrosis is caused by a gene with multiple alleles. Cystic fibrosis is inherited via incomplete dominance. Cystic fibrosis is a pleiotropic gene. Cystic fibrosis is caused due to polygenic inheritance.
