WebHuman population has 4 blood groups—A, B, AB and O. These are identified by a specific glycoprotein substance, called antigen on the surface of RBCs. The blood group is determined by a gene “I” which has three forms or alleles viz., I A, I B, I O. The genes I A and l B are dominant to gene I O but are co-dominant to each other and both ...

WebBlood groups are inherited from both parents. The ABO blood type is controlled by a single gene (the ABO gene) with three types of alleles inferred from classical genetics: i, I A, … WebGeographic Distribution of ABO Blood Groups. The frequencies of blood groups for the ABO system vary around the world. You can see how the A and B alleles and the blood group O are distributed geographically on the maps in Figure 6.5.6. Worldwide, B is the rarest ABO allele, so type B blood is the least common ABO blood type. WebBlood groups are inherited from our parents in the same way as other genetic traits (e.g. eye colour). The ABO blood group system is determined by the ABO gene, which is found on chromosome 9. The four ABO blood groups, A, B, AB and O, arise from inheriting one or more of the alternative forms of this gene (or alleles) namely A, B or O. can chronic stress injure the heart

WebBlood Type Is Determined Genetically. The A and B antigen molecules on the surface of red blood cells are made by two different enzymes. These two enzymes are encoded by different versions, or alleles, of the same gene. The A allele codes for an enzyme that makes the A antigen, and the B allele codes for an enzyme that makes the B antigen. WebThere are 4 different blood types – A, B, AB and O. These names indicate whether the blood’s red cells carry the A antigen, the B antigen, both A and B antigens, or neither antigen.
