Is cystic fibrosis a rare disease?
Yes, it is a genetic, inherited disease where a child must receive 2 alleles for cystic fibrosis in order to exhibit symptoms. If a child only receives one of the recessive alleles, they are known as a carrier because they have the ability to pass that gene on to their children.
To get information into its carrier wave every radio station has to amplify the carrier wave?
False.
Who invented the air conditioning?
Willis Carrier over a period of time from 1902 though 1911. He is the founder of the Carrier Corporation and Carrier brand air conditioners. There are several sub-brands, Bryant, Day-and-Night.
Why carrier signal is always in analog signal?
It isn't always. Baseband analog signals have no carrier.
Am single-sideband full carrier?
single sideband full carrier
Can a genetic counselor use a karyotype to identify a carrier of cystic fibrosis why?
No, a karyotype looks at the physical structure of the chromosomes. Cystic fibrosis is caused by mutations in the CFTR gene. Karyotypes cannot identify a mutation at the base pair level, only large deletions, duplications, rearrangements of the chromosomes. It would be comparable to trying to use a magnifying glass to look at electrons.
An individual heterozygous for cystic fibrosis?
Is a carrier of cystic fibrosis
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.
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.
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 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.
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
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.
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.
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 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.
