What are is the percentages of a child not having cystic fibrosis with parents who both have the trait?
If both parents are just carriers of the gene that causes CF then there is a 75% chance that the child will not have CF. To break it down farther... 25% chance that they will have CF. 50% that they will be a carrier. 25% that they will have two normal genes.
Can a b positive and a positive have a b negative child?
No. If both parents are positive, the child will be positive. If both parents are negative, the child will be negative. Parents who are negative and positive can have children who are either positive or negative. '+' + '+' = '+' '-' + '-' = '-' '+' + '-' = '-' or '+'
What is the probability that the next two children will both be affected with galactosemia?
A) 1/16
How can a child with cystic fibrosis have two parents that do not have cystic fibrosis?
The parents will both have a specific gene defect. If they do there is then a 1 in 4 chance of them having a child with cf. so if you are considering having children you should have a blood test to find out if you are a carrier of the gene causing cf. hope that helps.
Can child be born with sickle cell if one parent is sickle cell carrier and another is normal?
A child has to receive the gene from both parents to heve sickle cell anemia. if only one parent passes on the gene, then the child will have sickle cell trait, but no symptoms of sickle cell anemia.
Are there carriers for albinism?
Yes. If either parent is a carrier of the gene that causes albinism then their child becomes a carrier as well. It is only when both parents have the gene for albinism that the child is born with this disorder.
Are there any other ways to get cystic fibrosis?
No, it is a hereditary disease meaning it's only in the family and oth parents have to hold the gene for the child to get CF, you have to be born with CF you can't get it like the flu. Say the mother was a carrier of the CF gene but the Dad is not, the child would only be a carrier, but if both parents are then it's likely the child will have CF

A child with both parents dead are called?
A child with both parents dead
If the father has sickle cell trait and the mother doesnt will their children have sickle cell trait?
No. The trait that causes sickle cell anemia is a recessive trait, which means that if both parents have the trait, there is a 1/4 chance their child will have it. The child can be a carrier however and not display symptoms, but there is no way for a child to get sickle cell from parents that don't have the gene.
Can you prevent cystic fibrosis?
The only way to prevent CF is to get both parents tested before conceiving then making the difficult decision to go ahead and conceive (if both tested as a carrier of the CF gene). If both parents are carriers its a 25% chance of the child having CF.
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.
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.
Is it safe to have a child if both parents are 0 negative?
Can parents with both negative blood have a child and how much of a chance for that child having a dissabillity
What could be the reason why a child is born with A blood types and both parents are O plus could the parents parent be a carrier of A blood type?
Parents should re-test their blood types to check if there was any error in their past result. there is no way to have A blood type baby if both were O
If both parents are O positive can they have a child that is A positive?
No. If both parents are type O, the child will be O. If both are A, the child can be either A or O. If both are B, the child can be either B or O. If both are AB, the child can be A, B, or AB (but not O).
If both parents are carriers what will the child be?
When a recessive trait is inherited from both parents, it will be expressed. If the trait is hemophilia, the child will be a hemophiliac.
