Both members of a couple know that they are carriers of the cysticfibrosis allele. None of their three children has cystic fibrosis, but anyone of them might be a carrier. The couple would like to have a fourthchild but are worried that he or she would very likely have the disease,since the first three do not. What would you tell the couple? Would itremove some uncertainty from their prediction if they could find outwhether the three children are carriers?
