Blood Type Lab Report

b. The blood type (e.g., Type A, B, AB, O) of a group of participants (Mode)

2. Can the student tell from the blood type if the student is heterozygous or homozygous? Explain. (5 points) Yes, knowing your blood type would

3. At this point, you are ready to begin the lab exercise. Click on the “Information” button on the blood

10. Type A: The genotype is either AA or AO. The antigens on the blood cell are A and the antibodies in the blood plasma are B.

The group started by testing the controls. The group then added two drops of a blood sample to spot A and spot B on a blood typing slide. After the blood samples were added to the spots, the group added the appropriate antiserum to each of the samples. The group stirred each blood type and antiserum for 10 seconds with a clean toothpick.

There are four blood types found in humans. These are A blood type which has the genotype either AA or AO, B blood type which has the genotype either BB or BO, AB blood type which has the genotype AB, and O blood type which has the genotype OO. These genotypes show a combination of complete dominance and codominance. A and B traits are dominant to the recessive O trait, however, the A trait is codominant to the B trait. Each blood type codes for certain antigens. A blood codes for the A surface antigen, B blood codes for the B surface antigen, AB blood codes for both the A and B surface antigen, and O blood does not code for a surface antigen. Therefore to determine one’s blood type a test can be performed

The goal of this experiment is to determine the blood types of the samples given and to learn what interactions occurred to each blood type. Determining an individual’s blood type and how it reacts with Anti A, Anti-B, and Anti Rh serums played a crucial part in this experiment. The researcher concluded that agglutination (clumping) occurred in some of the blood samples. For example, Mr. Smith’s blood reacted with Anti-A and Anti-Rh serums (antibodies) allowing the researcher to determine the blood type is A. Mr. Jones’s blood reacted with Anti-B serum but it did not react to Anti-A or Anti Rh allowing the researcher to believe that the blood type is B. Mr. Green’s blood reacted with all serums and caused a reaction to occur resulting the blood type to be AB positive. Mr. Green’s blood also had a positive marker for Rh factor. However, Ms. Brown’s blood had no reaction at all and the researcher determined if no reaction occurred then the sample had no antigens but proved to have some antibodies, resulting in blood type to be O. The purpose of this experiment is to determine whose blood has type A, B, AB, or O.

For this experiment student will identify the individual blood types through the antigen and antibody reaction by using the anti- A, Anti- B and Anti- Rh serums we will be able to identify the different types of blood. Red blood cells also known as erythrocyte are small cells shaped like an oval however they have a plasma membrane but no nucleus. Hemoglobin is the protein that allows the red blood cells to bind easily with oxygen. While hematopoiesis is known as blood cell formation. The independent variable would be the Red blood cells. While the dependent variable would be the Antibodies and the antigens

The blood samples were put with Anti-A serum and Anti-B serum. The blood found at the scene clumped with Anti-B serum but not with Anti-A serum. Anna Garcia’s blood clumped with Anti-B and not with Anti-A serum. This means that Anna’s and the blood found found at the scene had Type-B blood. Alex Garcia’s blood sample clumped with Anti-B and and not with Anti-A, just like Anna Garcia’s and the blood from the scene.

To name the two major components of blood and state their average percentages in whole blood.

Blood typing is a way to identify and match blood samples. Three separate tests are performed. The patient 's blood is mixed with antibodies that bind to the A protein. If the patient 's blood clumps or agglutinates, that means that the person 's blood contains protein A. If the blood being tested does not react with the antibodies that bind the A protein, then that person 's blood does not contain protein A. Similar testing

To test the blood, we first dropped two drops of blood into two spots in a micro-well plate, then we added the appropriate serum to both and mixed with a small stick. One side was labeled A, for the A Anti-Serum, and one was labeled B. If the A blood clotted it meant that the A antigen was found, and likewise with B. If both clotted the blood type was AB, and if neither clotted the blood was type O. Some errors made

This table helps show all the possible genotypes from one set of parents. The table shows that the genotypes purple and starchy are dominant, and the genotypes yellow and sweet are recessive.(stallsmith)

Blood grouping involves the use of ABO system as described by Karl Landsteiner. The grouping came into existence in the year 1900 after discovery by Nobel Prize winner Karl Landsteiner. He first discovered three blood types A, B, and O, but after two years he discovered the fourth blood group AB. This discovery led to four major types of blood that includes A, AB, B and O. The grouping depends on the presence of two chief antigens and antibodies. The two antigens responsible for blood grouping include A and B while the antibodies include anti-A and anti-B. The combination of the two antigens and antibodies thus determines the blood types. The blood type A has antigen A and antibody anti-B. The blood group B express Antigen B and antibody anti-A (Reid and Lomas, 2004). Blood group O express no antigen but possess antibodies

The pairs of alternative traits examined segregated among the progeny of a particular cross, some individuals exhibiting one traits, some the other
