Concept explainers
a.
To determine: The ABO genotype of the three individuals.
Introduction: The blood group of an individual is determined by the presence of a certain kind of antigen on the surface of blood cells. A, B, AB, and O are four major blood groups found in human beings. The determination of the blood type of an individual is essential before the process of blood transfusion.
b.
To determine: The conclusions made by the court during the paternity suit.

- Explain the following: A. Explain briefly the mechanism behind clumping of blood after the addition of the anti-sera. B.Blood typing is one of the tests employed in paternity testing. Explain how the blood typing result is used in paternity testing. An example may be given to elaborate your answer.arrow_forwardAt the end of the day, Rina is already feverish, with dry cough and a throat that really hurts when she swallows. Succeeding days revealed that the doctor and assistant's condition did not get better. Both were brought to the hospital by their respective families and COVID test were done to them. Please answer the following and limit answers to one sentence for each. 1. What is a carrier? 2. Describe the following: a. asymptomatic carrier b. symptomatic carrier c. incubatory carrier d. convalescent carrier e. chronic carrierarrow_forwardIX. The blood of several members of a particular family was determined, and the results are tabulated below. Individual Blood Type Genotype Father Mother B Child 1 AB Child 2 B. Child 3 Grandfather (mother's side) Grandmother (father's side) AB Assuming that no adultery or adoption took place for all generations, answer the following questions: a. Give the most probable genotype for each individual. Supply your answers on the table above. b. What is/are the most probable genotype(s) for the grandmother on the mother's side? c. If the father and the mother decide to have two more children, what is the probability that the first would be female type A and the second male type AB?arrow_forward

What is required to demonstrate the presence of cells carrying a weak D antigen? 4. Explain the mechanism behind the existence of Dº. 5. Cite possible situations in which an attending physician would request for an emergency screening for the presence of "D" antigen.arrow_forwardA 6-year-old girl with chronic anemia requiring repeated blood transfusions is undergoing genetic testing. The patient's mother and older sibling have a history of mild anemia. Her peripheral blood smear shows hypochromic, microcytic red blood cells, and sickle cells. Doctor has expressed opinion to use electrophoresis for diagnosis. Please explain how may it work for this disease?arrow_forwardI understand that microarrays are being used to define the molecular abnormality and the prognosis in some patients with leukaemia.

Hemophilia is an x-linked disease in which the blood does not clot normally; it is sometimes called "bleeder's disease." Hemophilia is caused by a recessive allele (h). The dominant allele (H) produces blood that clots normally. What is genotype of a man who is a hemophiliac? What is the genotype of a man with normal blood clotting? What is the genotype of a woman with normal clotting blood if her father was a hemophiliac? If a man with normal clotting blood and a heterozygous woman have children together, what would you expect for the genotypes and phenotypes of the children? 13. A dominant x-linked allele (B) gives normal color vision but the recessive allele (b) causes red-green color blindness. What is the genotype of a man with normal color vision whose father was color- blind?arrow_forwardA 47-year-old obese female complains of pain in her right wrist, with tingling and numbness in the thumb and index and middle fingers for the past 2 weeks. She has been frustrated because the pain causes her to drop her hair-styling tools. A. What are possible 5 differential diagnosis for this case and why? B. What diagnostic testing would support this diagnoses and why?

- Phenotype: A2B 1. Give the possible genotype/s of A:B 2. If you were to perform the blood typing of this individual, what are the expected results given the following reagents Phenotype Forward typing (reagents) Reverse typing (reagents) Anti-A Anti-B Anti-H A cells B cells Al Write "+" for presence of agglutination and "-" for absence of agglutination 3. Explain the results of the blood typing, why would there be a "+" or a "" reaction during the testing. Relate your answer to the presence/absence of antigens and/or antibodiesarrow_forwardits itslearning /pdf-reader?job3D1617581334468 ... Tools ▼ A young woman in Hollywood sued a famous movie actor for support of her child, claiming that he was the father of her child. By typing the blood of the three persons involved, the following results were obtained: The child is type B; the Mother is type A; the Actor is type O. Could the actor have been the father? Explain. 5.arrow_forwarduan used the ABO blood testing kit to determine his blood type.
