Homework Answers
Answer: A. Agglutination.
Agglutination process is used for determining the blood group. It is an antigen-antibody reaction and it is the process in which antigens bind with its specific antibodies forming visible clumps. During the agglutination reaction, the insoluble RBC antigens binds with the soluble antibodies (Anti-A or Anti-B) and forms visible clumps. For the blood typing, a drop of blood is added on to slide coated with Anti-A on one end and Anti-B antibody on the other end. The person having blood group A will have anti-B antibodies in the blood, hence, agglutination will take place on the Anti-B coated side of the slide. If the blood group is B, then the agglutination will takes place on the Anti-A coated side. If no agglutination reaction takes place, the blood group is AB. Agglutination reaction with both Anti-A and Anti-B is not present, then the blood group is 'O'.
Precipitation is a process is the process in which the ions present in the solution reacts leading to the formation of insoluble clumps. Precipitation process occurs for the soluble antigen and antibodies. The RBC antigens are insoluble in nature.
Ouchterlony test is a type of immuno diffusion used for the detection and quantification of antigens and antibodies present.

a.) ABO blood types are determined by a single gene with 3 alleles. Alleles A (IA) and B (IB) are co-dominant to allele O (i). Cecilia, a woman with blood type A whose father and mother both had blood types AB, marries a man named Joseph. Joseph has blood type B. Joseph’s mother had blood type O. What is Cecilia’s genotype with respect to blood type? b.) ABO blood types are determined by a single gene with 3 alleles. Alleles...

A microsope slide showing agglutination when blood is mixed with antisera. our red blood cells are much stronger antigens and large aggregated clumps will be readily visible when agglutination has occurred. If you have neither A nor B antigen on your red blood cells, you will have no agglutination of either antisera and therefore the cells are blood type 0. Figure 4 shows a picture of aggluti-nation when cells clump or aggregate. No agglutina-tion is a smooth suspension of cells...

Background INFO
There are four types of blood: A, B, AB, and O (Figure 4). Each
is characterized by the glycoproteins (proteins with a sugar
attached) and lipoproteins (proteins with a lipid attached)
embedded in the surface of red blood cells (RBCs). In addition to
type, blood can be rhesus (Rh) factor positive or negative.
These proteins are inherited and may differ from individual to
individual. If, during a transfusion, an individual receives
blood with the incorrect RBC proteins (for...

ABO blood types are determined by 3 alleles at an autosomal locus: IA and IB are codominant, and iO is recessive. Assuming H-W equilibrium, if the frequency of the iO allele is 0.1 and the frequency of the IAallele is 0.6, predict the frequency of all 4 blood types in the population (type A, type B, type AB, and type O).

Human blood types A, B and O are associated with the carbohydrate antigens A, B and H respectively. A and B antigens are caused by an alteration of H antigen. Normally everyone can synthesize H antigen (a cell surface carbohydrate found on red blood cells and other cell types). Some people make A and/or B transferase(s) which converts the H antigen to an A and/or B antigen respectively. The H antigen is produced by a specific fucosyltransferase encoded by the...
