Web17 jul. 2024 · Your blood group depends on which antigens occur on the surface of your red blood cells. Your genetic make-up, which you inherit from your parents, determines which antigens are present on your red blood cells. Your blood group is said to be: A+ (A positive) if you have A and rhesus antigens. WebThe expression of ABO blood group antigens is determined by the interaction of three genes: the ABO gene, which controls expression of the A and B antigens; the FUT1 or H gene, which controls expression of the H antigen, the precursor of ABO antigens; and the secretor gene, FUT2 or Se.

Web25 aug. 2024 · ABO Blood Group: The inheritance of the AB blood type is an example of codominance. Therefore, the inheritance of the AB blood type follows the patterns of non-Mendelian inheritance. RH Blood … WebInheritance of Blood Groups. In this section, we will briefly describe several general principles that apply to how most blood groups are inherited. Most blood group genes are co-dominant. For example, in the ABO system, A and B genes are co-dominant; in the Rh system, C and c are co-dominant; and in the Kell system, K and k are co-dominant 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. north bay ski racers
