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)

Is sickle cell anemia recessive or dominant?
Sickle cell anemia is an autosomal recessive disease. Carriers have sickle cell trait, which confers resistance to malaria.
Is sickle cell an dominant or recessive?
Sickle cell anemia is an autosomal recessive disorder. It can result from two carriers having a child together.
Is sickle cell anemia dominant or receive?
recessive
Is sickle cell disease a chromosomal abnormality?
sickle cell is an autosomal recessive disorder
Is sickle cell anemia genetic or environmental?
Sickle cell anemia is genetic. It is an autosomal recessive disease.
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.
For sickle-cell disease assume S is the dominant allele and s the recessive allele Which genotypes are possible for offspring of a carrier (Ss) and a person who lacks the sickle-cell allele (SS)?
SS,Ss
Is sickle cell disease autosomal or x-linked or chromosomal?
Sickle cell is a sex-linked trait, If some one is a carrier than the trait is passed down on that chromosome.
Is sickle cell anemia an autoimmune disease?
Sickle Cell Anemia is Autosomal Recessive. It arises from a mutation on the beta-globin gene of chromosome 11. Because Sickle Cell Anemia is an example of incomplete dominance, a person has the disease if they have two mutated beta-globin genes but only has the trait (is a carrier) if they have only one mutated beta-globin gene.
Why does sickle cell disease run in families yet is not present in every generation?
It's because Sickle Cell is a recessive trait.
Compare the inheritance of Huntingtons disease with the inheritance of sickle cell anemia?
Huntingtons disease is Autosomal dominant, i.e. a 50% chance of inheritance if one parent has the gene. Where as sickle cell anemia is autosomal recessive. This gives a 25% chance of inheritance if both parents are carriers.
Can give example about overdominance?
Overdominance is when the heterozygote has an advantage over both the recessive and dominant homozygotes. Sickle cell disease is an example of this. When the individual is homozygous for the sickle cell allele, sickle cell disease is shown. When the the individual is homozygous for the wildtype allele, they appear normal. However, when the individual is heterozygous, he or she appears normal and will also be resistent to malaria.
