A couple who are both carriers of the gene for cystic fibrosis have two children who have cystic fibrosis What is the probability that their next child will be phenotypically normal?
If both parents are carriers on cystic fibrosis, just because two children may have the disease it doesn't mean that say,a further 3 children in future will be "normal". Inheriting genes is like a lottery. I can say though that because cystic fibrosis is recessive, every offspring born under carriers will always have a 75% chance of being phenotypically normal.
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.
How disorder is inherited cystic fibrosis?
Cystic Fibrosis, is a recessive disease (meaning that both parents must be carriers of the cystic fibrosis gene, for the offspring to have a chance of being born with it). A child has a 25% chance (1/4) of being born with 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.)
Why do inherited diseases like hemophilia and cystic fibrosis occur?
They are caused by the genes that we inherit from our parents. Genes govern how our body is run. Cystic fibrosis is caused by a recessive alle. This means that both parents must be carriers of the alle responsible for cystic fibrosis. The parents don't have to have the condition themselves; they can be just carriers of the one alle that makes up the condition.
Why can Cystic fibrosis be inherited even if neither parent has the disease?
Cystic Fibrosis is an example of a disease inherited as an autosomal recessive genetic disorder. Both parents of a baby who has Cystic Fibrosis have one abnormal recessive gene and one normal dominant gene and are therefore, Cystic Fibrosis carriers. Carriers are said to be heterozygous because they contain one normal copy of the gene and one abnormal copy. A baby who inherits cystic fibrosis has inherited the abnormal gene from both parents and is therefore said to be homozygous recessive.
How do you start a topic sentence if its about Cystic fibrosis?
What is cystic fibrosis? Cystic fibrosis is a life threatening disease.
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 most common fatal genetic disease in the United states?
cystic fibrosis (:cystic fibrosis :)cystic fibrosis ^-^
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.
Do girls have cystic fibrosis?
Yes, girls can get cystic fibrosis.
An individual heterozygous for cystic fibrosis?
Is a carrier of cystic fibrosis
