What else can I help you with?
If parents with normal pigmentation have an albino child what is the chance that their next child will have normal pigmentation?
The chance that their next child will have normal pigmentation is 75%. Albinism is usually caused by a recessive gene, so both parents would need to carry the gene in order to have an albino child. If both parents have normal pigmentation, then the chance of passing on the albino gene to their next child is 25%.
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.
Will a heterozygous female with hemophilia have blood that will clot normally?
Yes, because Hemophilia is recessive (if you have a normal allele, you won't have hemophilia, and heterozygous means that you have one normal and one abnormal allele).
If a man is heterozygous for the alleles that cause the condition and has children with a woman who lacks that defective allele?
If a man is heterozygous for the alleles that cause the condition and has children with a woman who lacks that defective allele, there is a 50% chance that each of their children will inherit the defective allele. This is because the man can pass on either the normal or defective allele, resulting in a 50% chance of passing on the defective allele.
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).
What is normal blood sugar and how can one get this?
The normal blood sugar for a non-diabetic person is below 5.7%. If you do not have this and you haven't been diagnosed as an diabetic, go to your doctor and they will advise you on how to proceed.
Individuals heterozygous for sickle-cell anemia appear normal and are resistant to what disease?
malaria
Is it normal for your blood sugar to go up and down if you are not diabetic?
Yes!
Is it possible for heterozygous parents of normal height to have only offspring with achondroplasia?
Yes, though it's rare. For each child the odds of that happening genetically is 25%) so to calculate the odds of n children of heterozygotic parents having that condition would be (1/4)n
What percentage of the offspring of a normal heterozygous (Dd) dog and a deaf dog (dd) would be expected to have normal hearing?
Fyugugy
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.
Is 97 to 120 blood sugar level within normal range for a non diabetic?
That is within normal range.
