Blood Typing Experiment 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

While child 3 cannot be classified as either Mr.Johnson or Mr.Wilson’s child. When looking at the control blood samples, A blood type forms “clumps” when mixed with the A antigen, B blood type “clumps” when mixed with the B antigen, AB blood type “clumps” with both the A and B antigen, and O blood type does not “clump” with either antigen. To the right are the individuals’ sample trays. Looking at each individual’s blood samples, Mr.Johnson had A blood, Mr.Wilson had B blood, Child 1 had A blood, Child 2 had B blood, and Child 3 had O blood. This supports the claim because knowing Mrs.Johnson’s blood type is O means Mrs.Johnson has the genotype OO. Due to the individuals’ blood types it is known that Mr.Johnson has either the genotype AO or AA, Mr.Wilson has either the genotype BO or BB, Child 1 must have the genotype AO because Child 1 must have had an O trait from Mrs.Johnson, Child 2 must have the genotype BO because Child 1 must have had an O trait from Mrs.Johnson, and Child 3 must have the genotype OO because that is the only genotype for type O blood. When looking at the children’s genotypes it can be concluded that Child A must be Mr.Johnson’s child because it inherited an A trait which can only come from Mr.Johnson, Child 2 must be Mr.Wilson’s child because it had to inherit a B trait which can only come from Mr.Wilson, however Child 3 could come from either Mr.Johnson or Mr.Wilson depending on which individual has a genotype that can pass an O trait. It is not possible from this test to tell whether it is Mr.Wilson or Mr.Johnson that passed on the O trait. Every other research group agreed with our claim. Each group had come to the conclusion that Mr.Johnson was the father of one of the three children
During this lab each group had to figure out who did the crime based on their blood type and dominant hand. To figure out which hand is the criminal’s dominant hand you have to figure out which hand they would have used to break in. The window that was staged as the crime scene was on the left side of the room, meaning the criminal would have needed to use their right hand to break the window and get inside. At first, I thought the person that did the crime was Mr. Padilla. I thought Mr. Padilla could have been the criminal because he does not have any children, which means that he has more time on his hands to do more things.
9. No, because each child's 2 sets of chromosomes are rearranged independently, so that there is an equal probability of all of them having the same genotype (1/2^4, or 1/16) as there is of them having all different ones
4. Clear wing, Black eye, and Hairless (c, b, and h) are linked, recessive traits carried on
Blood type is the type of blood a person has that is passed down from the parents. The goal of this experiment was to find out if all the children were Mr. Johnson’s. The guided question was “Are all of Mr. Johnson’s children his biological offspring?” This relates back to the background information because the group had to find the blood type of each child and relate it to Mr. Johnson’s blood type.
In this project, C. Elegans are hermaphrodite worms that will be used since they are easy to maintain in lab, as well as have short life cycles. The gene that the project attempted to knockdown in C. Elegans with RNAi treatment is the unc-22 gene. RNAi disrupts gene expression in the presence of double stranded RNA (dsRNA) that is complementary to target gene sequence. The unc-22 gene codes for a muscle protein called twitchin in wild-type worms. The Unc-22 is required for muscle regulation and maintenance in C.Elegans. To verify that the RNAi treatment worked, would check the unc-22 mRNA levels in the worms, in addition to phenotype observation.
The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in
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.
Since, the patient’s blood type is B+, he can safe and sound receive blood types B+, B-, O+, and O-. The blood types B+, B-, O+, and O- are well-matched with this patient Type B+, and supported with the point that he merely has the B antigen on red blood cells and an A antibody in the plasma. In the case of where the person has blood group O means that the person has neither A nor B antigens on red cells
Can the angle of a fatal blow be determined by the locations of the victim’s bloodstains? I will be comparing multiple bloodstains to one another and measuring them, trying to determine the angle at which I struck the “victim” (a kitchen sponge). This practice, called bloodstain analysis, is used by forensic investigators to determine the cause, position, and even time of death. I believe that by using trigonometry, I will be able to establish the angles at which I hit each sponge. I will repeat the experiment multiple times, and each blow will be delivered from a different angle.

Hypothesis – With the antigen and antibody reaction we can determine ABO and Rh blood types by using certain antiserums. If an A Antigen ever comes in contact with an Anti a antibody then the blood will have a reaction. Also if a B Antigen comes in contact with a B anti body then the blood will
Blood typing is a vital part of saving lives. People who have lost blood in any way will most likely need a blood transfusion. If the wrong type of blood is administered into their system, that person’s body will reject the new blood and the person will die. However, by knowing what antigens and antibodies are in a certain type of blood, the transfusion can be matched to the patient’s blood, which will lead to a safe, effective transfusion.Therefore, knowing what antigens and antibodies are in a person’s blood and what their blood type is can be a vital part of saving their life one day. For this reason, it is vital to know how antibodies affect blood typing.
The blood grouping systems commonly used include the ABO system that was first described by Karl Landsteiner. The discovery of blood grouping systems helped to avoid unnecessary death emanating from blood transfusion. The basics of blood grouping systems lie behind the inheritance of genes. The possession and inheritance of blood groups attribute to the parents who combine alleles responsible for the blood groups. The parents thus play a pivotal role in determining the blood groups of the offspring. This paper will work towards the discussion of inheritance of human blood groups.
Hello, I'm Kayden Dibble. I'm a chemist. For three years now I have been working on a serum to bring the dead back to life. My sole purpose for starting this project is because my wife was murdered and I swore I would . The good news is that the serum is completed. Now I just have to figure out what to test it on.
