10. In the following questions, identify the type of inheritance. Some questions may have multiple terms that apply.

Terms:

Simple Dominance, Codominance, Incomplete dominance, Multiple Alleles, Pleiotropy, Epistasis, Norm of Reaction (environmental effect) , Polygenic, Continuous variation, Linkage, Epigenetics-X inactivation, Epigenetics-Genomic Imprinting, Extranuclear inheritance

6) An individual is heterozygous for blood type. This person’s red blood cells produce both the A antigen and the B antigen.

7) Human height is influenced by many genes and by the environment and nutrition that an individual experiences.

8) Flower color in a newly discovered plant is controlled by one gene. There are three different variant forms of the gene in the plant population.

9) The Law of Independent assortment predicts an equal amount of parental (nonrecombinant) and recombinant type offspring when the double heterozygote is crossed with the double recessive, but when the offspring are counted, there is a much greater amount of parental nonrecombinant offspring. The relatively small number of recombinants is a result of crossover.  

10)Offspring are heterozygous for a dominant trait but only express their father’s recessive allele. The maternal gene is “written on” to turn off expression for the life of the individual.  

11)Two genes interact with each other to influence coat color. The first gene controls the ability to make coat pigment (A). The recessive allele blocks pigment production. If pigment can be made, the second gene codes for either brown color (B) or white (b).  

12)A mother passes her trait to all of her children but only her daughters can pass it to their children. The genes are unchanged generation after generation unless mutation occurs.

3. Being endothermic provides certain advantages to birds and mammals – they can have a much higher activity level than ectothermic taxa, and they can be active when ectotherms typically cannot, e.g. at night and in very cold areas such as those at high elevations or high latitudes. However, endothermy requires a number of changes in various body systems to work. Birds and mammals have solved the problems associated with endothermy and higher activity levels using some of the same solutions, but also different ones that achieve the same end. Give some examples of those solutions.

Consider the following scenario: Teresa Ann Campo Pearson was born anencephalic due to a congenital birth defect. That is, she was born without a brain. As a result of her condition, Teresa would only live for a few days or a few weeks. Further, even if she lived longer, she would never develop preferences, ideas, likes, dislikes, or a personality, because she lacked the parts of the brain that facilitate those things. In fact, Teresa would never be conscious at all. She would never feel pleasure or pain, and would never even know that she existed. Babies are born every day in the United States that, for one reason or another, need organ transplants. Teresa's parents knew this, and wanted to donate her organs to other children who did have brains and who might very well live long, healthy lives if they could receive Teresa's heart, lungs, liver, and kidneys. However, if Teresa died naturally her organs would be unsuitable for transplant, and if her organs were harvested prior to her death then organ harvest itself would kill her. The physicians in charge of Teresa's care objected to the wish of her parents, and their decision to refrain from organ harvest was upheld in court. Use the concepts you have acquired and the skills you have developed in this course to argue for a course of action in this scenario. You should do this in a short essay. The central questions you should answer are: should the organs be harvested? If so, why? If not, why not? Your position should be supported with an ethical theory covered in this class. You should briefly explain the ethical theory and how it renders moral judgments in general. Then you should explain how the theory applies to this case. Next, explain how a rival theory might be used to render a different decision, and explain what is good about that rival position. However, also explain why you think your position is the better position to take on the issue. Lastly, include a concluding paragraph that summarizes your essay. Some additional questions you may find it useful to answer (or at least to consider) are: What are the central ethical dimensions of this case? Who can be harmed or helped in this scenario? Is this case a moral dilemma, and if so, why? What is the slippery slope, and how does it figure into this case, if at all? This test assesses your knowledge from the entire course, and you can use no more space to answer the question than is provided below. This means you must focus only on relevant information and avoid all extraneous material.

Question text

In drosophila (fruit flies):

  • The yellow gene is on the X-chromosome, the gene product plays a role in body colour. Wild type flies are a light brown/tan in colour, homozygote yellow mutants have a more yellow shaded body colour. We'll use y+ to represent the wild type allele, and y to represent the mutant allele. y+ is dominant to y.
  • The vestigial gene is on chromosome 2. Homozygote vestigial mutants have very short wings, and cannot fly. We'll use vg+ to represent the wild type allele, and vg to represent the mutant allele. vg+ is dominant to vg.
  • The scarlet gene is on chromosome 3. Homozygote scarlet mutants have bright red eyes, while wild type flies have darker brownish-red eyes. We'll use st+ to represent the wild type allele, and st to represent the mutant allele. st+ is dominant to st.
  • Males are usually XY, and females are usually XX

You cross a female fly who is wild-type in phenotype and heterozygous for all three genes, with a male who has a yellow body, very short wings and bright red eyes. What is the probability their offspring will have very short wings and normal eyes, if body colour doesn't matter (i.e, they can be either yellow or wild-type in colour)? For full marks you must show your work.
