Web1 sep. 2024 · There are four main ABO blood type groupings: A, B, AB, and O. These blood groups are determined by the antigen on the blood cell surface and the antibodies present in the blood plasma. Antibodies (also called immunoglobulins) are specialized proteins that identify and defend against foreign intruders to the body. WebHuman ABO blood type is determined by a single gene that comes in 3 distinct alleles: IA , IB , and i. The IA and IB alleles are each dominant to the i allele, but are codominant with each other, meaning that both phenotypes are expressed in the heterozygote. The Punnett square below shows a cross between two parents with different blood types.

Blood 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 , and I . The I designation stands for isoagglutinogen, another term for antigen. The gene encodes a glycosyltransferase—that is, an enzyme that modifies the carbohydrate content of the red blood cell antigens. The gene is located on the long arm of the ninth chromosome (9q34). diary jones

WebWhen identifying a patient’s blood type, the Rh group is designated by adding the word positive or negative to the ABO type.

WebABO inheritance patterns The ABO blood group system is determined by the ABO gene.
