Even if both parents are carriers of the cystic fibrosis gene, their child will only have a 1 in 4 chance of developing the disease. You probably don't have much to worry about here, especially since the father is of Hispanic heritage. Only 1 in 46 Hispanics even carry the CF gene. Conversely, about 1 in 25 people of European descent are CF carriers.
