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.
How do black people get cystic fibrosis?
The Same Way Any other person would get CF (Cystic Fibrosis), although it's Very Rare For African Americans to get it. Cystic Fibrosis is most common among Caucasians.
What is a punnett square for cystic fibrosis?
A Punnett square for cystic fibrosis would involve crossing two parents who are carriers of the recessive allele for the disease (denoted as "cf"). The square would show the probability of having a child with cystic fibrosis (25%), a carrier (50%), or unaffected by the disease (25%). Each parent would have a genotype of "Cf" (carrier) for the Punnett square.
What genotypes would the parents need to have in order to potentially have a child with cystic fibrosis?
In order to potentially have a child with cystic fibrosis, both parents would need to be carriers of the recessive gene for the condition. This means that both parents would need to have the genotype "Aa" for the child to have a chance of inheriting the condition.
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).
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
Will the offspring have cystic fibrosis if the mother is FF and father is Ff?
No. Cystic fibrosis is an autosomal recessive disease. Each parent would have to be a carrier of a CF mutation and would be Cc.
Which of your friends would be more vulnerable to give you cystic fibrosis?
Cystic fibrosis can't be "caught". It is an inherited disease passed down in the genes to family members.
What is the genotype of two normal parents who have a child with cystic fibrosis?
The genotype would have to be homozygous recessive if the child was completely effected by the disease. The "normal" paretns would have to have heterozygous recessive genotypes. This makes sense since the allele that causes sickle cell shows incomplete dominance when present with a normal allele in a pair. The "normal" parents actually would have a mixture of sickle cell shaped red blood cells combined with normal shaped ones. The carrier parents does not display symptoms of the disease since the regular red blood cells alone can fill the body's need for oxygen under normal circumstances. The only time the cArrier would notice would be under times of extreme oxygen demand, such as a sprint.
Why would lipase be low?
Low lipase levels often point to problems with the pancreas. It can also indicate that the person has cystic fibrosis.
Does religion have an impact on cystic fibrosis?
Unfortunately, cystic fibrosis cannot be cured by prayer. If it could be cured by prayer, the disease would have disappeared a long time ago, because there are a great many people praying all the time. We have a great abundance of prayer, in this world. But we still have cystic fibrosis.
Why should 2 persons with cystic fibrosis not interact?
If two people with cystic fibrosis were to have children then the kids would also have it. Also, cystic fibrosis is a pretty nasty disease. It's where the mucus that protect organs etc becomes thick and sticky and the person with it often ends up with serious lung diseases or intestinal infections which can be dangerous, painful and expensive. But it's the parents who are the ones choosing whether they want this for there children.
