If someone is a carrier of the cystic fibrosis gene, will they develop any symptoms?
Nope. Cystic Fibrosis is autosomal recessive which means both genes must be abnormal (that is, have cystic fibrosis ‘trait’) in order for it to show. If the person is a carrier, that means that there is one dominant gene (no Cystic Fibrosis), and on recessive gene (having Cystic Fibrosis). Hope that helps! Good luck!
