ABO blood group system. The ABO blood types were discovered by Karl Landsteiner in , for which he received the Nobel Prize in Physiology or Medicine in ABO blood types are also present in some other animals such as rodents and apes, including chimpanzees, bonobos, and gorillas.
ABO Blood Groups: Predicting the Blood Type of Your Children. Note from the table that this mother could have created a child with type A blood with a father of any of the four possible blood types, typeA, type AB, type B, or type O. Likewise, the father of the child could be either Rh+ or Rh-.
Oct 01, · Characteristics. There are four common blood groups in the ABO system: O, A, B, and AB. The blood groups are defined by the presence of specific carbohydrate sugars on the surface of red blood cells, N-acetylgalactosamine for the A antigen, and D-galactose for the B antigen. Both of these sugars are built upon the H antigen—if Cited by: 4.
Blood groups are inherited from our parents in the same way as other genetic traits (eg, eye colour). ABO and Rh are the most well-known among the blood group systems. ABO inheritance patterns. The ABO blood group system is determined by the ABO gene, which is found on chromosome 9. ABO blood group system is the only group in which individuals have antibodies in their serum to: Carl Landsteiner Discovered the ABO blood groups in by .
Blood group antigens. For example, changes in a few DNA building blocks (nucleotides) in the ABO gene give rise to the A, B, and O blood types of the ABO blood group. The changes that occur in the genes that determine blood group typically affect only blood type and are not associated with adverse health conditions, although exceptions do occur.
ABO blood group system. A blood type is a classification of blood based on the presence or absence of inherited molecular substances (called antigens) on the surface of red blood cells. From: Research Methods in Human Skeletal Biology, ABO blood group system. 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.

Blood 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.
