What is a punnett square for sickle cell anemia?
Since you did not specify what parental cross you wished to represent this is the best I can do for you. A "normal" male would be represented as XHYo - gametes XH and Yo A male with hemophilia would be represented as XhYo - gametes Xh and Yo A female non-carrier would be represented as XHXH - gametes XH A female carrier would be represented as XHXh - gametes XH and Xh A female with hemophila would be represented as XhXh - gametes Xh
What if man who is carrier for sickle cell amonia a recessive genetic disease non carrier women what proportion of their children are expected afflicted with sickle cell amonia?
I'm guessing you meant sickle cell anemia. You already said that it's recessive, which means that both parents have to be carriers for it to be passed on to their children. If both parents carry the gene, then there is a 1 in 4 chance of having an affected offspring, 2 in 4 chances of having offsprings which carry the disease, and 1 in 4 of the child being unaffected (check out how to draw a punnet square). If one parent is a carrier and the other one is healthy, then you have a 50% chance of having an offspring who carries the disease, but none of your offsprings will be affected. Hope this helps
What are the chances that these parents will have three children who are homozygous for normal red blood cells if the parents both have sickle cell trait?
If both parents have sickle cell trait, they each carry one normal allele (A) and one sickle cell allele (S). The possible genotypes for their children are AA (normal), AS (carrier), and SS (sickle cell disease), with a probability of 25% for each genotype. Therefore, the chance of having three children who are homozygous for normal red blood cells (AA) is ( (0.25)^3 ), which equals 1/64, or about 1.56%.
How is sickle-cell disease a representation of codominance?
It's not sickle-cell itself, but rather being a heterozygous carrier of the disease. People with one dominant and one recessive allele for the disease are immune to malaria without the crippling effects of having sickle-cell anemia. I don't think that it can even represent codominance, though.
In the genetic pedigree person U and her husband are considering having another child What is the percent chance that this child will develop sickle cell disease?
If both U and her husband are carriers of the sickle cell trait, there is a 25% chance that their child will develop sickle cell disease. This is because there is a 50% chance the child will inherit one sickle cell gene from each parent, resulting in the disease.
How do you get sickle cell disease?
You can prevent sickle cell disease by theres no way you can but if you have sickle cell disease you can get blood transfusions to stop most of the pain becasue you can get new blood cells instead of moon like shaped cells and then you will have easier blood flow and no pain because it wont clog anymore.
Being a carrier of sickle cell anemia means?
sickle cell anemia is caused by a recessive allele. so for it to affect someone, it means that the person must have received both recessive alleles from their parents. Being a carrier means that you have the recessive allele from one of your parents, but you have a normal dominant allele from the other parent, that means you are not affected by it but you are carrying it.

Is sickle cell disease dominant or recessive?
The disease is recessive, requiring both parents to carry the allele for the disease to be found in the offspring. If one parent has it, the offspring can also be a carrier, but it will be recessive, and the offspring will have normal RBC (red blood cells)
How does a person with one sickle cell different than two Sickle cell?
A person with one sickle cell is a "carrier". This means that they have the dormant cell in their genetic composition, and if combined with another with the "carrier" gene, they run the high risk on concieving a child with the blood disease-one who has two sickle cells. A person with two sickle cells, has the sickle cell disease and are carriers(The gene is not dormant but active). Hope this simplifies and explains it for you.
How is sickle cell anemia iherited?
Recessively, that means that both parents must be symptomless carriers then there is only a 1 in 4 chance that a given child will be born with the disease. Note: symptomless carriers have the strong advantage of being much more likely to survive malaria than "normals". Sickle cell disease is inherited through a single pair of genes (one gene from each parent), on chromosome 11. They must receive the gene from both parents in order to actually get sickle cell disease. If they receive one gene for sickle cell disease from one parent but a normal gene from another, they have "sickle cell trait." The genes that involve sickle cell control the production of hemoglobin (a protein) in red blood cells. Abnormal hemoglobin from sickle cell disease causes red blood cells to grow incorrectly. Persons with sickle cell trait are much more resistant to malaria (a common disease in Africa, where the gene originated) than persons having two normal genes. This makes the sickle cell gene very likely to persist in areas where malaria is endemic, like Africa.

Sickle-cell anemia is a disease passed by autosomal recessive inheritance. What is the likelihood that a person who has two parents with the disease will be a carrier of the defective gene?
If both parents have sickle-cell anemia, their child will inherit one copy of the defective gene from each parent, making them a carrier. Thus, the likelihood that a person who has two parents with the disease will be a carrier of the defective gene is 100%.
Are sickle cell anemia and sickle cell trait the same?
No, sickle cell anemia and sickle cell trait are not the same. Sickle cell anemia is a severe form of the disease caused by inheriting two sickle cell genes (one from each parent), leading to significant health complications. In contrast, sickle cell trait occurs when an individual inherits only one sickle cell gene and one normal gene, typically resulting in no symptoms but allowing the person to pass the trait to their offspring.
How is sickle-cell disease a representation of codominance?

What is the name of blood test that says you are 'AA' or 'AS or'SS'?
The blood test is called a hemoglobin electrophoresis test, which is used to determine an individual's hemoglobin genotype. A result of 'AA' indicates normal hemoglobin, 'AS' indicates sickle cell trait (carrier), and 'SS' indicates sickle cell disease.
