 The ABO blood types are examples of 
The ABO system consists of A, B, AB, and O blood types. People with type A have antibodies in the blood against type B. People with type B have antibodies in the blood against type A. People with AB have no anti-A or anti-B antibodies.People with type O have both anti-A and anti-B antibodies.ismatches with the ABO and Rh blood types are responsible for the most serious, sometimes life-threatening, transfusion reactions. But these types of reactions are rare. For every 1 million units of blood transfused, getting the wrong blood type happens, at the most, 4 times. The ABO blood type system in humans is an example of: a) multiple alleles and codominance. b) balanced polymorphism and codominance.c) codominance but not multiple alleles. d) balanced polymorphism but not codominance.e) multiple alleles but not codominance.Add your answer.

Add your answer. Source. There are four principal types: A, B, AB, and O. There are two antigens and two antibodies that are mostly responsible for the ABO types. The specific combination of these four components determines an individual's type in most cases.ndividuals with type O blood do not produce ABO antigens. Therefore, their blood normally will not be rejected when it is given to others with different ABO types. As a result, type O people are universal donors for transfusions, but they can receive only type O blood themselves. For example, a person who is blood type A will have anti-B antibodies directed against the B antigens on red blood cells and someone who is type B will have anti-A antibodies directed against the A antigens. People with type AB blood have neither of these antibodies, while those with type O blood have both.f the Rh protein is present on the red blood cells, a person's blood type is Rh+ (positive); if it is absent, the person's blood is type Rh- (negative). Our bodies naturally produce antibodies against the A and B antigens that we do not have on our red blood cells. The most well-known and medically important blood types are in the ABO group. They were discovered in 1900 and 1901 at the University of Vienna by Karl Landsteiner in the process of trying to learn why blood transfusions sometimes cause death and at other times save a patient.ndividuals with type O blood do not produce ABO antigens. Therefore, their blood normally will not be rejected when it is given to others with different ABO types. As a result, type O people are universal donors for transfusions, but they can receive only type O blood themselves. Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells. A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs).lood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells. A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). The human ABO blood type is a good example of multiple alleles. Humans can have red blood cells that are of type A (I A), type B (I B), or type O (i).he human ABO blood type is a good example of multiple alleles. Humans can have red blood cells that are of type A (I A), type B (I B), or type O (i). For example, people with type A blood will have the A antigen on the surface of their red cells (as shown in the table below). As a result, anti-A antibodies will not be produced by them because they would cause the destruction of their own blood.ndividuals with type O blood do not produce ABO antigens. Therefore, their blood normally will not be rejected when it is given to others with different ABO types. As a result, type O people are universal donors for transfusions, but they can receive only type O blood themselves. Answers. Best Answer: multiple alleles and codominance, because if you have a dominant A blood allele and a dominant B blood allele, you get the codominance of having AB blood.nswers. Best Answer: multiple alleles and codominance, because if you have a dominant A blood allele and a dominant B blood allele, you get the codominance of having AB blood. The Antigens (agglutinogens): The different blood types in the ABO system arise from the existence of similar molecules on the RBC membrane (see Figure 1). In each type (A, B, or O), the base unit is the same-a protein with a lipid known as ceramide associated with it.he ABO System of Typing Blood. Human blood can be typed into Type A, Type B, Type O or Type AB blood because of the existence of similar molecules embedded in the membrane of the red blood cells. This section of the online activity explains how those blood types arise.
