you need two parents to get it but one parent to become a carrier.
You need two parents with one of the alleles to inherit it but if you have one parent with the allele you might be a carrier. If you have two parents with the allele it does not mean that you will definitely have it. This is because the allele for cystic fibrosis is recessive.
What else can I help you with?
What genotypes would the parents need to have in order to potentially have a child with cystic fibrosis?
In order to potentially have a child with cystic fibrosis, both parents would need to be carriers of the recessive gene for the condition. This means that both parents would need to have the genotype "Aa" for the child to have a chance of inheriting the condition.
Cystic fibrosis autosomal dominant?
hey I'm not positive but I believe that Cystic Fibrosis is autosomal. My reasonning for this is that there seems to be an equal number of females that have cystic fibrosis as there are males. I AM NOT POSITIVE.
Will a newborn screening test show positive for cystic fibrosis if only one parent is a carrier?
A newborn screening test for cystic fibrosis typically detects the presence of elevated levels of immunoreactive trypsinogen (IRT) in the blood, which can indicate the condition. However, a newborn can only have cystic fibrosis if both parents are carriers of the defective CFTR gene. If only one parent is a carrier, the child will not inherit the disease, but may still be tested as a carrier. Therefore, a positive newborn screening result may indicate the need for further testing to confirm the diagnosis.
How does a person becomes infected with cystic fibrosis?
The mother and father both have one mutated cystic fibrosis gene. If the child receives genes from the mother and the father that are both mutated, then the child will develop cystic fibrosis. If the child receives only one chromosome containing the CFTR(cystic fibrosis transport regulator: the gene that is mutated in cystic fibrosis), then the child will not develop CF. He will still have the CF gene, but it is a recessive trait, so you need two of these chromosomes that contain the mutated gene to develop the symptoms of CF and be affected by it. Use a punnet square if you still don't understand :)
If both parents have cystic fibrosis what is the probability that one child will have it?
It depends weather or not the woman carries the cystic fibrosis alele. If she carries a recessive CF allele, then the chances of her and the man having a child with CF is 1/4 But if she doesn't carry it then the child wont have CF but could carry the disorder as a recessive allele. again, the chances of that are 1/4.

What does cystic fibrosis have to do with heredity?
cystic fibrosis is hereditary but your children will only have a chance at having it if there are at least four children its a one in four kinda thing but they will need to get tested for being a carrier of the cf gene
What resaerch is being done on cystic fibrosis?
Unfortunately, cystic fibrosis cannot be cured. There is medication getting better all the time but now, the government in the UK have not funded in any cure. This means that in the UK, we may only find a cure if a devoted medical professional actually spent his own time to find the cure
What is the genotype of two normal parents who have a child with cystic fibrosis?
The genotype would have to be homozygous recessive if the child was completely effected by the disease. The "normal" paretns would have to have heterozygous recessive genotypes. This makes sense since the allele that causes sickle cell shows incomplete dominance when present with a normal allele in a pair. The "normal" parents actually would have a mixture of sickle cell shaped red blood cells combined with normal shaped ones. The carrier parents does not display symptoms of the disease since the regular red blood cells alone can fill the body's need for oxygen under normal circumstances. The only time the cArrier would notice would be under times of extreme oxygen demand, such as a sprint.
Is cystic fibrosis an infectious disease?
Good Question. The answer is cystic fibrosis is not contagious, however, people with cystic fibrosis tend to carry bacterial infections that can cause serious issues to other people with CF, so infection control procedures should be used when two or more cystics are around each other. General population folks need not fear of getting cystic fibrosis from others - it's a hereditary disease.
Is CF X-linked or incomplete dominance?
Cystic fibrosis (CF) is an autosomal recessive disorder, not an X-linked disorder. It means that both copies of the gene responsible for CF need to be mutated in order to develop the disorder. Incomplete dominance refers to a genetic trait where the heterozygous condition results in an intermediate phenotype, which is not the case for CF.
What two parts of the body are affected by cystic fibrosis?
cystic fibrosis means there is too much fluid in the lungs and it makes it very hard for them to breathe. It also affects their growing and their digestive system because of the mucus. Unfortunately even a small cold can make them very sick because it affects the lungs. Unfortunately they usually die in their 30's and it is a very serious disease that more people need to be educated about.
