yes there are two concentrations of sickle cell
they are:
sickle cell trait: co-dominance is established and only 50% of your cells are malformed
sickle cell anemia: sickle cell is totally dominant and all cells are malformed, this only happens when both alleles are coded for sickle cell
What else can I help you with?
The genetic disorder sickle cell disease is an example of heterozygous dominance?
Sickle cell disease is an example of codominance, not heterozygous dominance. In individuals who are heterozygous for the sickle cell allele, they exhibit a milder form of the disease called sickle cell trait, which demonstrates codominance of the normal and mutant hemoglobin alleles.
What disease are you immune to if you are heterozygous for sickle cell disease?
malaria
Do individuals who are heterozygous for sickle-cell anemia have a greater resistance to malaria?
Yes, individuals who are heterozygous for sickle-cell anemia have a greater resistance to malaria due to the presence of the sickle cell trait which makes it more difficult for the malaria parasite to survive in the red blood cells.
What is the word for the genetic disorder that causes abnormal hemoglobin is known as?
sickle cell anemia. If you are only heterozygous for this disease it is simply called sickle trait.
What is the genotype for sickle cell anemia?
homozygous recessive (rr) & Heterozygous (Rr) homozygous recessive (rr) & Heterozygous (Rr)
How does balancing selection affect the sickle cell allele in central Africa?
The sickle cell allele can be maintained in the central African population, above the frequency of gene mutation (balancing selection), because the heterozygous sickle cell individuals have an advantage in lifespan, in this malaria stricken region, over the homozygous alternatives. Homozygous sickle-sickle individuals die early from the sickle cell disease. Homozygous nonsickle-nonsickle die early from malaria. The heterozygous sickle-nonsickle have a higher survival against malaria and therefore the sickle cell allele is balanced selected.
Individuals heterozygous for sickle-cell anemia appear normal and are resistant to what disease?
malaria
What is the advantage of being heterozygous for the sickle cell allele?
Sickle cell trait carries a lower risk of serious malarial disease, without the signs and symptoms of sickle-cell anemia.
What genetic disorder can be beneficial in its heterozygous form?
Sickle Cell Anemia, in it's heterozygous form it does not present as the disease and it gives the carrier resistance to malaria.
Can heterozygous for sickle cell have greater resistance?
Yes, individuals who are heterozygous for the sickle cell trait (having one normal hemoglobin allele and one sickle cell allele) can have greater resistance to malaria. The presence of the sickle cell allele provides some protection against the malaria parasite, as the altered shape of the red blood cells makes it less hospitable for the parasite to thrive. This selective advantage is particularly observed in regions where malaria is endemic, leading to a higher prevalence of the sickle cell trait in those populations.
What is the genotype of a man who has sickle cell trait?
rr since sickle cell is a recessive trait.
How are people that are heterozygous for sickle cell disease generally healthy?
because ur moma said so
