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.

Why do people of Mediterranean and African decent have sickle cell anemia?
Sickle cell anemia is a inherited blood disorder. This means everyone who has sickle cell has inherited it from their parents. With this in mind it means there was a key ancestor in Africa or the Mediterranean who had the first sickle cell anemia and passed it on to their descendants.
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
Is sickle cell anemia inherited as a dominant or recessive trait, and how does this inheritance pattern impact the likelihood of developing the condition?
Sickle cell anemia is inherited as a recessive trait. This means that a person needs to inherit two copies of the sickle cell gene (one from each parent) to develop the condition. If only one copy of the gene is inherited, the person is a carrier but does not have the disease. This inheritance pattern impacts the likelihood of developing the condition because both parents must be carriers for there to be a chance of their child having sickle cell anemia.
Does tionne watkins daughter have sickle cell anemia?
no she is an carryier for it that means she carries the disease but its not like her moms
Is sickle cell anemia a sexlinked trait?
Nope! The disease is equally in both males and females. This means that it is autosomal.
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.
Is sickle cell anemia a sex link trait?
Nope! The disease is equally in both males and females. This means that it is autosomal.
How Sickle cell anemia works?
Sickle cell anemia is a homozygous recessive disorder. This means that an individual must receive two homozygous alleles from each of their parents in order to be affected by the disease. This gene then produces an abnormal shape - a "sickle" shape - of hemoglobin, resulting in clots of blood as they cannot fit through narrow capillaries.
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.
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.
The allele for the sickle cell trait is what with the normal allele?
The allele for the sickle cell trait is codominant with the normal allele. This means that in individuals with both alleles present, both traits are expressed.
If a child is diagnosed with sickle cell anemia what does that mean?
Sickle cell anemia is a genetic disorder where red blood cells are misshapen, causing them to get stuck in blood vessels and leading to pain, organ damage, and other complications. It can cause episodes of pain, anemia, infections, and can affect multiple organs in the body. Treatment focuses on managing symptoms and preventing complications.
