A.

Cystic fibrosis occurs in children who have inherited two abnormal copies of a specific gene, one from each parent. A parent who does not have CF but has one normal copy of this gene and one abnormal copy is called a CF carrier. A child who receives a normal copy from one parent and an abnormal copy from the other will be a CF carrier and won't have the disease. Males and females are equally likely to inherit the disease.
