Answer to Question #320611 in Genetics for Justin

Question

Using what you know about dna, what does it mean for there to be a mutation in the cystic fibrosis gene

Answer 1

Cystic fibrosis (CF) is a genetic disease. This means that it is inherited. A child will be born with CF only if they inherit one CF gene from each parent.

Cystic fibrosis is an example of a recessive disease. That means a person must have a mutation in both copies of the CFTR gene to have CF.
