ABO Blood types and Hardy-Weinberg calculations

ABO blood group system, the classification of human blood based on the inherited properties of red blood cells (erythrocytes) as determined by the presence or absence of the antigens A and B, which are carried on the surface of the red cells. Persons may thus have type A, type B, type O, or type AB blood. The A, B, and O blood groups were first identified by Austrian immunologist Karl Landsteiner in 1901. See blood group. Blood containing red cells with type A antigen on their surface has in its serum (fluid) antibodies against type B red cells. If, in transfusion, type B blood is injected into persons with type A blood, the red cells in the injected blood will be destroyed by the antibodies in the recipient’s blood. In the same way, type A red cells will be destroyed by anti-A antibodies in type B blood. Type O blood can be injected into persons with type A, B, or O blood unless there is incompatibility with respect to some other blood group system also present. Persons with type AB blood can receive type A, B, or O blood. Problem: Out of the 355 Indians, the allele frequencies of O , A , and B blood alleles were , , and , respectively. Calculate the percentage of individuals with O, A, B, and AB type blood. #NikolaysGeneticsLessons #Genetics #ABOBloodGroup #populationGenetics #alleleFrequency #Genotype #Phenotype #hardyWeinbergAssumptions #hardyWeinberg #alleleFrequencies #genotypeFrequencies #hardyWeinbergEquations #hardyWeinbergPrinciple #HardyWeinberg #probabilityInGenetics #ABOGroup #bloodType #ABOBloodGroups #RhBloodGroups #blood #group #type #ABO #AB0 #zero #ab #system #classification #compatibility #incompatibility #factors #rhesus #factor
