If both parents are carriers then the child has a 25% chance of having cystic fibrosis.
If one parent has CF and the other the other was just a carrier then the child has a 50% chance of having CF.
If one parent has CF and the other has two normal genes then there is no chance of the child having CF.
If one parent is a carrier and the other has two normal genes then there is no chance of the child having CF.
If both parents have CF then there is a 100% chance that the child will also have CF.

If both parents have cystic fibrosis what is the probability that one child will have it?
It depends weather or not the woman carries the cystic fibrosis alele. If she carries a recessive CF allele, then the chances of her and the man having a child with CF is 1/4 But if she doesn't carry it then the child wont have CF but could carry the disorder as a recessive allele. again, the chances of that are 1/4.
What is the probability of a child having cystic fibrosis if one of her parents was homozygous dominant and the other was a carrier for cystic fibrosis?
Assuming that each parent is a carrier for cystic fibrosis (has the genotype Ff), the probability that their second child will develop cystic fibrosis is one fourth. The probability doesn't change with the number of children they have. For each pregnancy, the chance that the child will have cystic fibrosis (have the genotype ff) is exactly the same.
What is the inheritance pattern for the cystic fibrosis allele what is the reasoning for this conclusion?
If both parents have the gene, the chances are 25% of having a child with Cystic Fibrosis. The male and females x genes are affected by it and only half of it. So when the parents mate and they are going to have a baby, the chances are 25%
What are the chances of a normal person and a carrier for cystic fibrosis have a kid with cystic fibrosis?
Zero. Cystic fibrosis is an autosomal recessive disease. This means that both parents must carry a mutated gene and have a 1 in 4 (25%) chance of having a child with CF.
What are the possible phenotypes of the offspring between a parent who is a heterozygous carrier for cystic fibrosis and a homozygous normal parent?
The chances are one half. You will most likley have 2 children without the gene, and 2 with one gene. Since the normal parent has the dominate allele, the Cystic Fiborisis will not be present.
How can you detect cystic fibrosis?
Most babies with cystic fibrosis are diagnosed at birth from meconium ileus (stomach blockage) however if undetected at birth if a doctor is suspicious he can give the "sweat test" which measures the concentration of chloride that is excreted in sweat. for a further list of symptoms here's the cystic fibrosis website in the below related link.

Can an Adult get cystic fibrosis?
From what I understand there is no such thing as Adult Onset Cystic Fibrosis. CF is a hereditary genetic disease that you are born with. That said, there are rare cases of people with symptoms so mild they were not diagnosed until there 30s-60s. Sometimes these people have had prior medical problems but their doctors didn't check for CF because of their age. It is often so debilitating that children are diagnosed within the first few days of life. I am not an expert, I am just looking for research because I was told to go in for a test today (at age 33). The hospital couldn't even administer the test in the normal lab, I need to go to the children's hospital. I am just now reading http://www.cff.org/ it has more official information.
