Human Blood Type Inheritance

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

So in order to distinguish between groups they need a polymorphism that is located in all members of a group but missing in all members of another group. But humans have mixed too much for the differences to be present. Some polymorphisms have different frequencies and that is how they can roughly determine in which group a person belongs. They use a specific class of polymorphism that contains the Alus. Alus are pieces of DNA that are identical to one another. When an Alu infuses itself it will continue to stay there for generations, and it keeps getting transferred from one person to their offspring. So if they find two people with the Alu in the same location of each of their genome than it is certain that they have to be descendents from a common ancestor who also has the Alu in that same location in their DNA. There was an experiment held at the University of Utah, with a group of scientist, which used the 565 people and extracted 100 different Alus from each person. Their experiment concluded that they had 4 different groups of people. With this they discovered their country of origin and realized that to determine these they only needed about 60 Alus to have 90 percent accuracy. Some test concluded that some populations have experienced so much genetic influences that they cannot be placed into a specific group because of their genetic makeup.

Type AB: The genotype is AB. The antigens on the blood cell are A and B. There are no A or B antibodies in the blood plasma.

Of One Blood is a story about an African American character named Reuel Briggs, who is light enough to pass as white and manages to get into medical school. However, along with journey, he faces many challenges, including having to have to travel to Africa in an attempt to get away from poverty. W.E.B, Du Bios in his book The Soul of Black Folk discusses the hurdles confronted by African Americans. One of the main themes that are predominate in Of One Blood is the how great of a role identity plays in our lives. W.E.B Du Bois idea of the “double consciousness” and the “veil” that separates the black and white population adds depth to the theme of identity and challenges faced by people of color. This veil is where African American exited. WEB

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.

t all began in 1818 according to the Blood Centers of the Pacific the first recorded successful human blood transfusion was accomplished during this era. However due to the lack of knowledge and research, it was followed by many blood transfusion failures. But 80 years later, scientists discovered that our red blood cells are different from one another, which was the cause of many incompatibilities blood transfusions in the 1800's. Due to this four blood types were identified - A, B, AB and O. This discovery revolutionized hematology and led the way for successful blood transfusions.

The purpose of this experiment is to identify the different 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 blood types. We will also discuss how this can be used in the clinical setting of this blood typing procedure, by doing so we will know how antigens and antibodies relate to the blood typing procedure in the real world settings.

Anna Garcia is a 38-year-old Hispanic female, weighing 165 lbs.; standing 5'4 (64 inches) tall. She was last seen in a grey sweater, walking her dog at 6:30a.m the morning before, by her neighbor, Doug Greene. The same neighbor called police at 9:45a.m claiming that Anna's dog had been barking for approximately two hours and that Anna wasn’t answer the door or calls. She was found DOA lying in her hallway at her house. The body was found at 9: 56 am when police officers broke down her door.

To explain the ABO and Rh blood groups and to identify the universal donor and the universal acceptor (recipient).

A 13 year old is studying blood in school, and has asked some questions that haven't been answered in class. I will answer

First the de-originated blood goes into the right atrium. And the originated blood goes through the left atrium. The right atrium then pumps blood through the tricuspid valve into the right ventricle, and the left atrium pumps blood through the bicuspid valve into the left ventricle. The right ventricle contracts, semi lunar valve opens and deoxygenated blood travels back to the lungs. The left ventricle contracts, semi lunar valve opens and oxygenated blood goes out to the body.

Biology was the first class that helped me understand this phenomenon. Through genetics and Punnett squares, biology explained that my parents had heterozygous type B blood. I was different because I ended up receiving a homozygous type O blood from my parents. But as I explored genetics, I became engrossed by the process of inheritance and how genes are passed down to the next generation. Although some genetic mutations like the different blood types cause little to no harm, I

The system works because in blood there are antigens and agglutinogens. In type A, only type A antigens on the red blood cells. Similar to this type B only has type B antigens. Type AB has both A and B antigens, which is why it is the universal recipient. Type O has neither A or B antigens making it the universal donor.

This paper will discuss how phenotypes are driven by DNA inheritance in offspring by the genes known as alleles. Each parent provides an allele although on allele is hidden in one parent and can be passed on to his or her offspring. The information presented in the monohybrid cross that shows where one parent has the hidden allele of a gene that carries the trait of orange eyes that disappears and reemerges later in the genetic make-up of an offspring. The inheritance in the offspring is driven by the DNA of that individuals parents and the genetic traits one is born with are decided by the dominant and recessive genes of his or her parents (www.nature.com, 2014).
