Detailed explanation-2: -The disease occurs mostly in whites whose ancestors came from northern Europe, although it affects all races and ethnic groups. Accordingly, it is less common in African Americans, Native Americans, and Asian Americans. Approximately 2, 500 babies are born with CF each year in the United States.

The greatest risk factor for cystic fibrosis is a family history of the disease, especially if either parent is a known carrier. The gene that causes cystic fibrosis is recessive.

Detailed explanation-4: -Cystic fibrosis is the most common life-limiting autosomal recessive disease among people of European heritage. In the United States, about 30, 000 individuals have CF; most are diagnosed by six months of age. In Canada, about 4, 000 people have CF.
