Describe the chance of inheriting cystic fybrosis?

1)An individual who is homozygous (ff) with the recessive allele will develop cystic fibrosis. 2)Someone who is heterozygous (Ff) will be a carrier of the recessive allele, but will not develop cystic fibrosis and have no symptoms. 3)Someone who is homozygous with the dominant allele (FF) will not develop cystic fibrosis, as you need two faulty alleles (ff) for the condition. In this combination, no faulty alleles are present.
