If we denote a cystic fibrosis gene with a c and a disease-free gene with a c (since the disease is recessive), then only a cc person will actually have the disease. such persons would ordinarily die before parenting children, but a child can also inherit the disease from two cc parents (who themselves are healthy—that is, have no symptoms but are "carriers" of the disease). suppose a child is born to one cystic fibrosis carrier parent and one non-carrier parent. find the probability that that the child will be a carrier.
