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.
Does cystic fibrosis affect more males?
No, cystic fibrosis affects males and females equally. It is an inherited genetic disorder caused by mutations in the CFTR gene, which can be passed down from each parent who carries a mutated gene.
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
Is this true or false cystic fibrosis is caused by a mutation that is the dominant allele of a gene?
False. Cystic fibrosis is caused by a mutation in the CFTR gene, which is inherited in an autosomal recessive manner. This means that an individual must inherit two copies of the mutated gene (one from each parent) to develop the disease. If a person carries only one copy of the mutated gene, they are a carrier but do not exhibit symptoms of cystic fibrosis.
What is an inherited eventually fatal disease of the exocrine cells that is carried by a recessive gene?

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.
Does cystic fibrosis have extra chromosomes?
No, cystic fibrosis is caused by mutations in the CFTR gene, not by the presence of extra chromosomes. Individuals with cystic fibrosis inherit two faulty copies of the CFTR gene, one from each parent, which leads to the production of a defective CFTR protein that affects the movement of salt and water in and out of cells.
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 has gene therapy shown promise in controlling?
Gene therapy has shown promise in controlling genetic disorders such as cystic fibrosis, sickle cell anemia, and muscular dystrophy. It has also shown potential in treating certain types of cancer and inherited eye disorders.
Do carriers have to have cystic fibrosis?
Carriers of cystic fibrosis do not have the disease themselves, as they possess one normal copy and one mutated copy of the CFTR gene. However, they can pass the mutated gene to their children. For a child to develop cystic fibrosis, they must inherit two copies of the mutated gene, one from each parent. Therefore, while carriers do not have cystic fibrosis, they play a crucial role in its inheritance.
Is cystic fibrosis sex or gene linked?
Cystic fibrosis is primarily a genetic disorder caused by mutations in the CFTR gene, which is located on chromosome 7. It is not sex-linked, as the gene responsible for cystic fibrosis is not located on the sex chromosomes (X or Y). Both males and females can inherit the condition if they receive two copies of the mutated gene, one from each parent. Therefore, cystic fibrosis is considered an autosomal recessive disorder.
