What is sickle-cell disease and how is this disorder inherited?
Sickle-cell anemia is characterised by abnormal haemoglobin which are not the correct shape and cannot carry oxygen. It is a genetic disease - and a person must have two copies of the gene to have sickle-cell anemia. (Heterozygous individuals, with one copy, are known as having sickle-cell trait - and some of their haemoglobin may be misshapen).
What is it called when a person has two recessive alleles for sickle cell trait?
A person with two recessive alleles for sickle cell trait has sickle cell anemia. This genetic condition leads to the production of abnormal hemoglobin, causing red blood cells to become sickle-shaped and leading to various health issues.
Sickle cell anemia results from a defective?
Sickle cell disease is a group of disorders that affects molecule in red blood cells (hemoglobin) that delivers oxygen to cells throughout the body. Person with this disorder have typical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.
What condition is a person with only ONE sickle cell gene and one normal hemoglobin gene more capable of surviving than someone who has no sickle cell genes?
A person with one sickle cell gene and one normal hemoglobin gene has sickle cell trait, which can provide some protection against malaria. This advantage makes them more capable of surviving in regions where malaria is prevalent compared to someone with no sickle cell genes, who would be more susceptible to severe malaria infection.
Is sickle cell anemia a communicable or noncommunicable?
I don't know what a communitive disease is, and neither does the dictionary, but sickle cell anemia is an inherited abnormality. I hope that helps.If you are asking if sickle cell is a disease in which you can catch from other people. The answer is No. It is an inherited Blood disorder.
How many oxygen molecules sickle cell hemoglobin carry?
Sickle cell hemoglobin can carry one oxygen molecule.
Is it safe to marry a person with sickle cell?
it is safe to marry a person with sickle cell, provided that you are not a career of the trait.
Who invented the first sickle?

What is required for a person to have sickle disease?
The person is homozygous for the trait
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.
What is require for a person to have sickle-cell disease?
The person is homozygous for the trait
Where in the world are the most cases of Malaria and Sickle Cell anaemia?
Malaria is common in topical ad subtropical zones. The malaria has selected the people with sickle cell anaemia. Although person with sickle cell anemia can have malaria, the carrier, or the person with sickle cell trait is resistant to malaria.
How many amino acids need to be incorrect to prevent protein from working properly in sickle cell anemia?
Just one incorrect amino acid prevents protein from functioning properly in sickle cell anemia.
What groups get sickle cell disease?
A person can only inherit sickle-cell genes if some of their ancestors came from certain regions in Africa where the inhabitants carry sickle-cell genes. A person with one sickle-cell gene has sickle-cell trait, a milder problem. If both father and mother pass on sickle-cell genes, the child, with two genes, will have sickle-cell disease.
