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 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 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.

Why does a person with Cystic Fibrosis have the genotype cc?

Cystic Fibrosis is inherited as a recessive trait. This means that both parents have to carry the allele for the defect. Both parents are Cc which means that 25% of their children will be CC (homozyous dominant and will not be able to pass the recessive allele in subsequent generations, 50% will be Cc(carriers) and 25% will be cc (homozygous reccessive and have Cystic Fibrosis).


How is a child born with cystic fibrosis?

Cystic fibrosis is genetic and is not contagious A person gets it when he/she inherits two mutated genes off each parent. A healthy couple can have a child with Cystic fibrosis because the parents would be carriers of the disease (even though they are unaffected by it themselves). 25% of children are at risk of the disease as it can be passed down from previous generations.


Can cystic fibrosis kill the person who has it?

How do black people get cystic fibrosis?
