What else can I help you with?
Is it possible for a mother to have two kids with different father be born with cystic fibrosis?
Depends. If your mother has cystic fibrosis and your father is a carrier, there is a 50% chance that any of their children will have cystic fibrosis. If the father is not a carrier, no children will have cystic fibrosis, but they will all be carriers.
An individual heterozygous for cystic fibrosis?
Is a carrier of cystic fibrosis
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.)
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 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 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.
What is the probability of two healthy people where one is a carrier being parents to a child born with cystic fibrosis?
If only one person is a carrier of cystic fibrosis than there is no chance of having a child with it. Both parents have to be carriers and even then there is only a 25% chance. If only one carries than there is a 50% chance that their children will carry but will not have cystic fibrosis.
Does Cystic Fibrosis affect kids?
yes, everyone who has cystic fibrosis has had it from birth therefore they have it when they are children.
To be a cystic fibrosis carrier do your parents have to have a cystics fibrosis gene?
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.
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.
What health problems would i have if i carried the cystic fibrosis gene?
A carrier is someone who has a gene, but does not express that gene. It's like someone holding a book but is not capable of reading it. The carrier has no symptoms of the disease. The carrier can have a child with cystic fibrosis if the other parent is also a carrier of that gene.
Can people be carriers of cystic fibrosis and not know?
There are no symptoms or anything in a carrier of cystic fibrosis. The only way to find out is to get tested, or if you have a child with cystic fibrosis, you must be a carrier, as well as your partner.
