What are the chances of a normal person and a carrier for cystic fibrosis have a kid with cystic fibrosis?
Zero. Cystic fibrosis is an autosomal recessive disease. This means that both parents must carry a mutated gene and have a 1 in 4 (25%) chance of having a child with CF.
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 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.
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.
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
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.
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.
How can one child be born healthly and second one have cystic fibrosis?
To have a child with cystic fibrosis both parents must be a carrier or a sufferer. A carrier is a person who has one healthy gene, and one diseased gene, so they dont have cystic fibrosis but they can pass it on to their children. Children inherit one gene from each parent. To get cystic fibrosis a child must get two copies of the 'disease' gene - one from each parent. If two carriers have children, each child has a 25% chance not getting a Cystic fibrosis disease gene, 50% of being a carrier and 25% of being a sufferer. This is not affected by if the child is male or female. So essentially the answer is bad luck.
Is cystic fibrosis common?
Cystic fibrosis is the most common life threatening disease in the UKOne in 25 people have the cystic fibrosis gene in them (but may not have the disease). Most people aren't even aware that they carry the gene. If two people who have the gene reproduce, the odds that they have a child with cystic fibrosis is 1 in 4. The chance that they will have a child who carries the gene but doesn't have the disease is 2 in 4 (half). The chance that they have a child who does not have the disease or carry the gene is 1 in 4.
What would a genetic counselor tell parents who had cystic fibrosis or were carries of the cystic fibrosis about the chances of their children having cystic fibrosis?
If both parents are carriers then the child has a 25% chance of having cystic fibrosis. If one parent has CF and the other the other was just a carrier then the child has a 50% chance of having CF. If one parent has CF and the other has two normal genes then there is no chance of the child having CF. If one parent is a carrier and the other has two normal genes then there is no chance of the child having CF. If both parents have CF then there is a 100% chance that the child will also have CF.
How can you get cystic fibrosis?
For a baby to be born with Cystic Fibrosis, both parents must be carriers of the faulty CF gene. Where both parents carry the faulty gene, each child has a one in four chance of having CF, a two in four chance of being a carrier and a one in four chance of not having any CF genes.
