Cystic fibrosis is a autosomal recessive gene. That means that it may, but doesn't always have to skip generations. In order to have this disease, both parents must be carriers. If one parent has Cystic fibrosis and the other one is not a carrier than there is a 100% chance that their child will be a carrier. If one parent has Cystic fibrosis and the other is a carrier than the child has a 50% chance of having CF and a 50% chance of just being a carrier. If both parents are carriers than their child will have a 25% of having CF, a 50% chance of being a carrier and a 25% chance of not bein

One way which CF can be detected is to observe the symptoms. A person doesn't need to have all the symptoms in order to have cystic fibrosis, but they usually show most of them. Another way are different genetic testing. Doctors can now do genetic testing for CF, but about 10 years ago they couldn't. In 1989, the location where the of the defective gene on chromosome number 7 is was discovered by Francis S. Collins from University of Michigan.
