thank you!!
EXERCISE 9 THE ABO BLOOD SYSTEM Work with a small group or alone to answer the following questions about the ABO blood group system and blood type compatibility 1. Can a person with blood type A successfully receive a transfusion from a person who has type O? Why or why not? is the universal Since typer o bred 2. Can a person with blood type A successfully receive a transfusion from a person who has type...
EXERCISE 5 MENDELIAN TRAITS IN HUMANS 1 While most human traits are polygenic, the traits in the chart below have traditionally been considered Mendelian traits. More recent research has disputed the single-gene nature of some of these traits, but for the purpose of this exercise, assume that the following traits are Mendelian. Work with a partner to help each other determine your own phenotypes and possible genotypes for these traits. Write your answers in the chart. (Note: Refer to the...
EXERCISE 5 ABO BLOOD GROUP Work in a small group or alone to complete this exercise. Review Figure 8.6 (on p. 235). Use this information, as well as your understanding of the forces of evolution, to answer the following questions. 1. Many populations throughout central Eurasia share high frequencies of the B allele. What does this pattern suggest about the evolutionary history of these populations? Describe the evolutionary force that probably caused this trait distribution. 2. The 0 allele is...
The ABO blood group system is valuable in helping to settle cases of disputed parentage. The following table lists the blood types of various mother-child combinations. In each case list the blood types that can be excluded as possibilities for the father. Blood type of child Blood type of mother blood types that father cannot have O O O B A B B O AB A AB B
There are three main alleles in the ABO blood group system -
IA, IB, and i. We've talked about the ABO
system in class, you can find a brief explanation below and
here.
The I gene encodes for a glycosyltransferase
that modifies at the H antigen.
The glycosyltransferase encoded by IA adds an 'A'
sugar group to antigen H, the glycosyltransferase encoded by
IB adds a 'B' sugar group and i encodes an inactive
glycosyltransferase that leaves the H antigen...

Analyzing Genetic Data A. ABO Blood Group The human ABO blood group is an example of how three alleles that control a trait may interact. In this case, two of the alleles are codominant and one is recessive to the other two. The table below lists the phenotypic and genotypic data for this trait. Blood Type Phenotype Type A Type B Type AB | Type 0 Possible Genotype Ilori Pori | IAI 1. List the three alleles that control expression...
A and B are codominant over O in the ABO blood system. Another common way to type blood is with the Rh factor, in which Rh positive is dominant over Rh negative. A toddler has B positive blood. The mother has A negative blood. Potential father #1 has O positive blood. Potential father #2 has B negative blood. Potential father #3 has AB positive blood. Who is the child's father and why?
EXERCISE 1 MUTATION Work in a small group or alone to complete this exercise. In Lab 2, Exercise 8, you determined the amino acid sequence for the following strand of DNA: AGCAATCCGTCTTGG TCGTTAGGCAGAACC That strand has mutated. It is now AGCAACCCGTCTTGG TCGTTGGGCAGA ACC Use your knowledge of mutation and protein synthesis to answer the following questions 1. What mutation has occurred? 2. Will this mutation have a real effect? Why or why not? (Hint: You may want to try Exercise...
Tom and Jane participate in a Red Cross blood drive. Both are first-time donors. As part of the screening process, their blood is typed. Tom is Group A+. Jane is Group AB+. EMTs bring two accident victims into the emergency room at the hospital. One victim is bleeding from a head wound and needs a transfusion of blood cells to replace what she has lost. She is Group AB+. From this information, you conclude that Jane’s blood cells can be...
