Day 3 of cystic fibrosis information

Cystic fibrosis is a recessive disorder, which means that both parents must pass on the defective gene for any of their children to get the disease. If a child inherits only one copy of the faulty gene, he or she will be a carrier. Carriers don't actually have the disease, but they can pass it on to their children. About five percent of Caucasians (one in 28) are believed to carry the gene.
