Human blood groups are determined by what
WebBernstein in 1924 found that the blood group antigens are controlled by an autosomal gene designated I (iso-haemaglutinin) which has 3 alleles I A, I B and I O. Allele I A produces type A blood and is dominant over the allele I O which in the homozygous state (I O I O) produces type O blood. An A type individual can have the genotype I A I A or ...

WebHuman ABO blood groups are determined by a single gene with 3 alleles: A, B, and O. In a sample of 300 individuals, 100 are blood type A and genotype AA, 100 are blood type B and genotype BO, and 100 are blood type O and genotype OO. What are the allele frequencies? 33.3% A, 33.3% B, 33.3% O 33.3% This problem has been solved! WebADVERTISEMENTS: In this article we will discuss about the determination of blood group. Blood type (also called blood group) is a classification of blood based on the presence or absence of inherited antigenic substances (antigens) on the surface of red blood cells. If the red blood cell had only “A” antigen on it, that blood […]
