For a baby to be born with Cystic Fibrosis, both parents must be carriers of the faulty CF gene. Where both parents carry the faulty gene, each child has a one in four chance of having CF, a two in four chance of being a carrier and a one in four chance of not having any CF genes.

Why can Cystic fibrosis be inherited even if neither parent has the disease?
Cystic Fibrosis is an example of a disease inherited as an autosomal recessive genetic disorder. Both parents of a baby who has Cystic Fibrosis have one abnormal recessive gene and one normal dominant gene and are therefore, Cystic Fibrosis carriers. Carriers are said to be heterozygous because they contain one normal copy of the gene and one abnormal copy. A baby who inherits cystic fibrosis has inherited the abnormal gene from both parents and is therefore said to be homozygous recessive.
Why do only half of a carrier's gametes contain faulty cf gene?
only half of the carrier's gametes contain the cystic fibrosis gene because they only inherit one gene from either the mother or father, not both. For someone to have cystic fibrosis they must have inherited a faulty gene from each parent.
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 kind of pathogen causes Cystic Fibrosis?
Cystic fibrosis is not an infectious disease but a genetic disease, provoked by mutations fo the CFTR gene, mainly inherited.
How gene therapy might be used to treat cytic fibrosis?
In cystic fibrosis there is an inherited gene that you have that is causing it, so if gene therapy is used, you can replace the gene with the effected one
What is an inherited eventually fatal disease of the exocrine cells that is carried by a recessive gene?
cystic fibrosis
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.
Which gene causes cystic fibrosis?
Cystic Fibrosis is caused by the gene which codes for the protein CFTR--Cystic Fibrosis Transmembrane Conductance Regulator, which is found on chromosome 7. The protein transports chloride ions across epithelial cell membranes.
What does a CFTR gene stand for?
It is the gene for cystic fibrosis. CFTR means Cystic Fibrosis Transport Regulator.
Does cystic fibrosis have extra chromosomes?
No cystic fibrosis is caused by a mutated CFTR gene.
What has gene therapy shown promise in controlling?
Gene therapy has shown promise in controlling Cystic fibrosis.
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.)
