The difference between sickle cell trait and sickle cell disease?
It has to do with your genitic make up. You don't have sickle cell anemia because you only have 1 of the traits on your beta hemoglobin gene. People with sickle cell anemia have two.Most of the time peolple with sickle cell trait display much milder symptoms. It is more prevolent in African Americans and woman should be monitored during pregnancy.
Is sickle cell anemia the same as sickle cell diseases?
yes
How are sickle cell anemia and maleria the same?
They are definitely not the same. If you are looking for an answer to WHY sickle-cell anaemia is BENEFICIAL to those with malaria then follow this link,What_is_the_benefit_of_sickle_cell_anemia_to_Africans_with_malaria
Why does sickle cell anemia persist?
Primarily because of the same reason why any of us still persists, because even those people can reproduce. And it has been proven that people who has sickle cell anemia are immune to malaria.
Could the same genetic condition that causes sickle cell anemia can also protect against any other diseases?
A single sickle-cell gene protects against malaria. Two sickle-cell genes produce sickle-cell disease.
Why has sickle cell anemia been maintained in the human population?
Sickle-Cell AnaemiaSickle cell anemia is a disease that is controlled by alleles S and s .three possible combinations are SS , Ss ans ss . The most important reason why this allele is present in whole world including America is heterozygous superiority which keeps this gene in population Several major Universities whose main function is Technology, along with the Medical Schools associated with teaching in the Children's Hospitals have begun joining forces using nanotechnology to alter the genetics of the sickle cell trait. Among them is a collaborative effort between GA Institute of Technology, Emory University Medical School, and Children's Health Care Systems of Atlanta. Once this is accomplished, plans are already in the works to move on to another deadly disease initiated with inherited genes: Cystic Fibrosis. This is an excellent collaborative use of each genre's best abilities: cooperation vs competition.I earlier times this may have been negatively associated with eugenics, however that connotation is now being transformed with the positive aspects of actually changing genetics at the microcellular level to rid populations of certain killer traits, rather than attempts at 'perfecting the human race,' as in the despicable times of Hitler. This is not a genocidal experiment, but one aimed at saving lives of painful and deathly diseases, remembering sickle cell trait is mostly among Blacks.To get a clearer picture of why the allele is still present, just remember what the Hardy-Weinberg principle predicts:both allele and genotype frequencies in a population remain constant; that is, they are in equilibrium from generation to generation unless specific disturbing influences are introduced. Those disturbing influences include non random mating, mutations, selection, limited population size, "overlapping generations," random genetic drift, gene flow and meiotic drive.Since the homozygous recessive (when the Anaemia is actually expressed) and heterozygous condition do not affect mating probabilities, the allele will naturally remain within the population.
What does sickle-cell anemia do to the body?
Well reag anemia is where your red blod cells produced from bone marrow are very low in quantity. Your not having enough produced. Sickle cell is the same but the few being produced are shaped diff and in a way deformed and your RBC carry oxygen throughout body so with sickle cell the RBC u do have aren't healthy and can't appropriately deliver oxygen in reag anemia they can appropriately deliv oxygen but there are very few
Is there to many or too less chromosomes in sickle cell anemia?
Neither. People with sickle cell anemia have the same number of chromosomes and even the same number of genes as those who don't have the disease. The difference is a *change* in one of the genes. Actually, it is (usually) caused by a one letter difference in the hemoglobin gene which makes the hemoglobin produced more 'sticky' on a molecular level.
Is sickle cell anemia a disease from mutation?
Yes, but the mutation happened many many thousands of years ago. It has been passed on through all these generations because the same gene that causes sickle cell anemia in a person that inherits two copies of the gene also causes resistance to the malaria parasite in a person that inherits only one copy of the gene. In areas of the world where malaria is a common disease, the resistance to it is a stronger selective advantage than sickle cell anemia is a selective disadvantage; so the gene becomes very common in those populations.
The cause of sickle cell anemia is?
a child must inherit two copies of the defective gene in order to have a cystics fibrosis but when it come to sickle-cell anemia it is a disease passed down through families in which red blood cells from an abnormal sickle or crescent shape.Red blood cells carry oxygen to the body and are normally shaped like a disc so what causes sickle-cell anemia is the two copies that they get from both parents which gets passed down through families.
What people are most likely to develop sickle cell anemia?
there is no specific group of people can get this disease, but i can tell you that in some country you will find the majority of sick people accumulate in one region and that due to the marriage from the same place in this case the no. of sickle disease will increase in that particular area.
What is the medical term meaning erythrocyte with an irregular shape?
Sickle Cell Anemia is a genetic disease where the red blood cell (erythrocyte) takes on a sickle or crescent shape instead of the normal biconcave disk. Whereas the normal RBC is flexible and can easily travel through tight places in the joints, the sickle cell has no "give" and will bunch up in those same tight places causing inflammation, pain and heat.
