Cystic fibrosis results when patients Inherit two coples of a recessive CFTR gene. The recessive CFTR genes produce a protein which causes mucus to build up in parts of the body, Having just one
dominant CFTR gene allows the body to produce a normal protein, Individuals with one dominant
CFTR gene have no cystic fibrosis symptoms. Which question would BEST help researchers identify
a potential treatment for cystic fibrosis?

Explanation:

For Cystic Fibrosis to be inherited by an offspring, one must inherit not one but TWO copies of the recessive CFTR Genes, so those who have just one will obviously not inherit this disease. So answering your question, for researchers to identify a potential treatment for this disease, they must have answers to the following questions:-

Although there is no cure for this disease, what medicines like antibiotics would be most efficient to treat the disease?

What Other temporary treatments can be given to the patient?
