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.
The sequence of amino acids in cystic fibrosis is caused by a mutation in the CFTR gene, which leads to the production of a faulty cystic fibrosis transmembrane conductance regulator protein. This mutated protein results in abnormal function, leading to the characteristic symptoms of cystic fibrosis such as thick mucus production.
Two genetic disorders are Turner's syndrome and cystic fibrosis.
The genes on each chromosome control specific functions of the human body. The gene on chromosome 7 produces a protein called cystic fibrosis transmembrane regulator. Mutation in the DNA level of chromosome 7 leads to the absence of this protein which leads to cystic fibrosis. Cystic fibrosis is a recessive disease. It means that both copies of the gene must be defective. An affected person will have abnormal cystic fibrosis transmembrane regulator gene on each chromosome 7. Therefore both biological parents must have an abnormal gene. One abnormal copy is inherited from each parent. A person with one normal gene and one abnormal gene is called a cystic fibrosis carrier. Cystic fibrosis carriers do not show any symptoms but they may pass the abnormal gene to their children. Therefore the parents can be either cystic fibrosis carriers or affected themselves.
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.
Cystic fibrosis affects the respiratory, digestive, and reproductive systems.
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.)
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.
cystic fibrosis (:cystic fibrosis :)cystic fibrosis ^-^
Is a carrier of cystic fibrosis
Yes, girls can get cystic fibrosis.
To found Cystic Fibrosis, watch Princess and I!!!
