The Same Way Any other person would get CF (Cystic Fibrosis), although it's Very Rare For African Americans to get it. Cystic Fibrosis is most common among Caucasians.
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.
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
No. Cystic fibrosis is an autosomal recessive disease. Each parent would have to be a carrier of a CF mutation and would be Cc.
Cystic fibrosis can't be "caught". It is an inherited disease passed down in the genes to family members.
The genotype of a person with CF is cc. The genotype of a carrier of a CF mutation is Cc.
Cystic Fibrosis
Unfortunately, cystic fibrosis cannot be cured by prayer. If it could be cured by prayer, the disease would have disappeared a long time ago, because there are a great many people praying all the time. We have a great abundance of prayer, in this world. But we still have cystic fibrosis.
Yes, since the disease is a recessive inherted trait BOTH parents must carry the gene but will not have the disease itself. Approximately 30,000 people in the United States have cystic fibrosis. An additional ten million more-or about one in every 31 Americans-are carriers of the defective CF gene, but do not have the disease. The disease is most common in Caucasians, but it can affect all races.
phenotypes are decided by the alleles for that particular characteristic, by a dominant or two recessive alleles. For example, cystic fibrosis has a recessive allele so the phenotype of cystic fibrosis would only appear if there were two of the recessive allele, one from each parent, were present. A heterozygous carrier of the cystic fibrosis allele would show the phenotype of not having cystic fibrosis. So to determine the phenotype simply find out which allele is dominant and find what alleles each parent has the the probability of each phenotype can be calculated
You will usually get it when you are about 13 or 14. Some girls get it when they are 16.
