Is a carrier of cystic fibrosis
What else can I help you with?
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 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 are individuals who are heterozygous for the cystic fibrosis allele inaffected by the disease?
Individuals who are heterozygous for the cystic fibrosis allele carry one normal copy of the CFTR gene and one mutated copy. Cystic fibrosis is an autosomal recessive disorder, meaning that two copies of the mutated gene are required for the disease to manifest. The presence of one normal gene allows for sufficient production of the CFTR protein, which helps regulate salt and water transport in cells, preventing the development of the disease in heterozygous individuals.
When C equals normal allele and c equals allele for cystic fibrosis Set up and complete a Punnett Square for cystic fibrosis for a couple that both have heterozygous for cystic fibrosis with no sympt?
Sure! When both parents are heterozygous carriers (Cc) for cystic fibrosis, the Punnett Square would result in a 25% chance of having a child with cystic fibrosis (cc), a 50% chance of having a child who is a carrier (Cc), and a 25% chance of having a child who is not a carrier and does not have the disease (CC).
How do you start a topic sentence if its about Cystic fibrosis?
What is cystic fibrosis? Cystic fibrosis is a life threatening disease.
What is the most common fatal genetic disease in the United states?
cystic fibrosis (:cystic fibrosis :)cystic fibrosis ^-^
What does heterozygous have to do with cystic fibrosis?
people who are heterozygous for cystic fibrosis are not directly affected by the disease (although there is some evidence they have more chance of getting Asama) however they do still carry the gene for CF (they are carriers) this means if they have kids with another carrier they have a 25% chance of having a CF positive child (out of four one non effected, two carriers, and one diseased)
Do girls have cystic fibrosis?
