Cystic fibrosis is genetic and is not contagious A person gets it when he/she inherits two mutated genes off each parent. A healthy couple can have a child with Cystic fibrosis because the parents would be carriers of the disease (even though they are unaffected by it themselves). 25% of children are at risk of the disease as it can be passed down from previous generations.

How disorder is inherited cystic fibrosis?
Cystic Fibrosis, is a recessive disease (meaning that both parents must be carriers of the cystic fibrosis gene, for the offspring to have a chance of being born with it). A child has a 25% chance (1/4) of being born with Cystic Fibrosis.
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 genotype of an individual that is not affected with cystic fibrosis?
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.)
A husband and wife have a son with cystic fibrosis Their second child a daughter does not Prepare a pedigree for this family?
To have cystic fibrosis both parents have to be a carrier. Each parent passes on one of their genes to their children; they each have one healthy and one cystic fibrosis gene. The child with cystic fibrosis receives a cystic fibrosis gene from each parent. The other child has at least one healthy gene if she does not have cystic fibrosis, though she could be a carrier. hope it would help
What are facts on cystic fibrosis?
-Doctors take a sweat test to see if you have cystic fibrosis.-About 2,500 babies are born with cystic fibrosis each year.
If born with cystic fibrosis at birth can it go away?
No. Unfortunately there is no cure for Cystic Fibrosis at this time.
Is it possible for a mother to have two kids with different father be born with cystic fibrosis?
Depends. If your mother has cystic fibrosis and your father is a carrier, there is a 50% chance that any of their children will have cystic fibrosis. If the father is not a carrier, no children will have cystic fibrosis, but they will all be carriers.
Will a child with cystic fibrosis have liver problems?
No-False
How old is a child with cystic fibrosis?

How frequent is cystic fibrosis?
Cystic Fibrosis affects approximately over 9,000 people in the UK and is the most common genetic disorder. According to the Cystic Fibrosis trusts website, approximately five babies each week are born with Cystic Fibrosis.
What is the probability of two healthy people where one is a carrier being parents to a child born with cystic fibrosis?
If only one person is a carrier of cystic fibrosis than there is no chance of having a child with it. Both parents have to be carriers and even then there is only a 25% chance. If only one carries than there is a 50% chance that their children will carry but will not have cystic fibrosis.
