Ethyl and Egbert are starting their family. Ethyl has free earlobes, but her mother has attached earlobes; Ethyl is not able to roll her tongue. Egbert also has free earlobes, but he is able to roll his tongue. Egbert's son from a previous marriage has attached earlobes and is a non-roller.
What are Ethyl's and Egbert's genotypes for these two genes? Fill in your answers on the answer page.
If Ethyl and Egbert have a large family, what fraction of their children to you expect to have a phenotype (for these two traits) just like their mother, Ethyl? Fill in your answer on the answer sheet, and don't forget to show your work for this problem in the appropriate space on that page.

How is oxygen binding affected when the Val residue is mutated to serine?
| Substitution of valine with serine would increase the affinity of oxygen binding because the side chain of Ser increases the polarity of the binding site for oxygen, which is a polar molecule. |
| Substitution of valine with serine would increase the affinity of oxygen binding because the side chain of Ser increases the polarity of the binding site for oxygen, which is a nonpolar molecule. |
| Substitution of valine with serine would decrease the affinity of oxygen binding because the side chain of Ser increases the polarity of the binding site for oxygen, which is a polar molecule. |
| Substitution of valine with serine would decrease the affinity of oxygen binding because the side chain of Ser increases the polarity of the binding site for oxygen, which is a nonpolar molecule. |

while allergies are an example of type I hypersensitivities, there exist other hypersensitivities as well. Briefly describe type II, III, and IV hypersensitivities, including the immune component involved and how they result in overreaction of the immune system.

Last Sunday night at the local hospital was really busy, and the
folks in the maternity ward got just a little bit flustered. Two
pairs of twins were born that night within a few moments of each
other, but somehow the staff forgot to put name tags on the babies,
and now they don't know which babies belong to which parents. You
need to help them out by analyzing the blood types of these four
babies and the two couples who are anxiously waiting to take their
new families home with them.
Here's what you know:
You know about the inheritance patterns of human ABO blood types
You know the blood types of the two sets of parents:
Mrs. Smith is blood type A, and her husband is blood type B.
Mrs. Abernathy is blood type O and her husband is blood type AB.
And you know the blood types of the four babies (all little girls, incidentally):
Baby #1 is blood type O
Baby #2 is blood type A
Baby #3 is blood type B
Baby #4 is blood type AB
What could be simpler? On the answer sheet, tell me which two babies you're going to send home with Mr. and Mrs. Smith, and which you are going to send with Mr. and Mrs. Abernathy. (Please identify the babies by their numbers, shown above.) Then explainexactly how you figured it out. Show work as needed for your explanation, including Punnett squares for each of these couples.

Ellie May, a mother with type B blood, has a child with type O blood. she claims that Jethro, who has type A blood, is the father. He claims that he cannot possibly be the father. Based on this information only, is it possible that Jethro is the father?
If blood tests ordered by the judge revealed that the father is homozygous in genotype, is it possible for Jethro to be the father?
