Where can one find information on cystic fibrosis treatment?
An excellent source of information on cystic fibrosis, the Cystic Fibrosis Foundation can be accessed in a number of ways. Information on a local chapter can be accessed via phone at 800-344-4823.
What must be true of a person with cystic fibrosis?
Both parents had at least one allele for 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 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.)
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.
Is cystic fibrosis dominant or recessive?
Cystic Fibrosis is recessive. If you have one CF gene and one non-CF gene, you will be a carrier but not have CF.
Do people suffering with cystic fibrosis lack a chromosome or they have an extra one?
Neither. Cystic fibrosis is caused by genetic mutations on chromosome 7.
What is one treatment for cystic fibrosis?
there is no one treatment as different drugs treat different parts of the disease, however one essential drug is Creon enzymes which replaces the enzymes made in the pancreas of your body.
What is the type of inheritance of cystic fibrosis?
Cystic fibrosis is an autosomal recessive disorder caused by mutations in the CFTR (cystic fibrosis transmembrane conductance regulator) gene. Heterozygous carriers (those who have inherited only one copy of the altered gene) are asymptomatic (do not experience symptoms). Two of these altered genes must be present for CF to appear. This means that if both parents are CF carriers, their offspring will express CF symptoms only if the child inherits one defective copy of the CFTR gene from each parent.
What is the inheritance pattern or cystic fibrosis?
Cystic fibrosis is an autosomal recessive disorder caused by mutations in the CFTR (cystic fibrosis transmembrane conductance regulator) gene. Heterozygous carriers (those who have inherited only one copy of the altered gene) are asymptomatic (do not experience symptoms). Two of these altered genes must be present for CF to appear. This means that if both parents are CF carriers, their offspring will express CF symptoms only if the child inherits one defective copy of the CFTR gene from each parent.
What would be the genotype of a person with cystic fibrosis?
The genotype of a person with CF is cc. The genotype of a carrier of a CF mutation is Cc.
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.
