Let's call the gene "C." Capital C means no cystic fibrosis; lower c means cystic fibrosis, since it is a recessive gene. CC is a person who does not have cystic fibrosis and also is not a carrier. Cc indicated a carrier. cc shows a person with cystic fibrosis. In order for a child to have cystic fibrosis, its parents must be:
1. cc and cc (both have cystic fibrosis, so every child will as well.)
2. Cc and Cc (both carriers; 25% chance of having a child with cystic fibrosis)
3. Cc and cc (one parent is a carrier and one has cystic fibrosis; there is a 50% chance that the children will have cystic fibrosis.)
The genotype of a person with CF is cc. The genotype of a carrier of a CF mutation is Cc.
Is a carrier of cystic fibrosis
haha. right.
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.
Cystic fibrosis affects the respiratory, digestive, and reproductive systems.
The lungs (pulmonary surfactant is missing or diminished).
cystic fibrosis is a Genetic disease and in the case of cystic fibrosis, it's not affected others by any external medium like air , water etc that mean it's not a communicable disease.
What is cystic fibrosis? Cystic fibrosis is a life threatening disease.

Yes, girls can get cystic fibrosis.

No. Cystic fibrosis is a genetic disease.
