Document Summary

Practice midterm multiple choice questions up to the lecture on cytoplasmic inheritance. Note that the answers are provided at the end of the document. These questions reflect the questions that will be found in the midterm. There will be ~50 questions, each worth 1 mark. It is suggested that you first try to answer the questions and then look at the answers at the end of this document. If you find there are areas where you are weaker, go back and study that material more and possibly go to a study session if necessary. The questions in this practice midterm go up to the lecture on cytoplasmic inheritance. Assume that recombination does not occur between the z and w chromosomes. These two genes include the f gene that controls female fertility, and the ms gene that controls male fertility. The following phenotypes and genotypes are associated with each allele:

She is agitated states"leave me alone. I am in perfect health and know my own mind." Her mother and boyfriend arrive and state that she has been taking lithium carbonate 600mg t.i.d. for Bipolar Disorder II for the past 5 years, with good results until several weeks ago. Her boyfriend states that she has been 'up all night' for the past few days and has a "harebrained scheme to become a Rhodes Scholar". Miss B's mother states that she suffers from chronic depression and that she is worried since Miss B is pregnant. She says, "I have bad genes, but is there anything that we can do to keep my grandchild from having a mental disorder?" Case Study Guidelines: You will be divided into groups of 3 to 6 (based on enrollment). Each group will respond to the questions in the case study. Each group will place their report in the drop box by the due date listed by the week. Absence from the group presentation will result in the deduction points for the individual. Case Study Guidelines: Each will respond to the questions in the case study. Diagnosis: What test should be done? Who should be tested? What are the implications of the results? What do you think the results will be and why? In addition include a pedigree 1. Identify additional information/history that should be elicited in relation to this case. 2. Identify the pattern of inheritance for the disease/condition, and discuss the reason for your answer. 3. Identify family members that may be at risk for this disease, explain your answers. 4. Discuss any other alternative explanations for the disease/condition pattern noted in the Pedigree. Please refer to the book: Genetics and Genomics in Nursing and Health Care(2012)

General Instructions This essay should be 400-500 words in length. You must use correct spelling and proper mechanics. You must include citations and a reference list for any resources used at the end of this essay. It is expected that you will use one to two references for this essay topic. Essay #2 Studies of identical and fraternal twins have yielded some very interesting information on the genetic basis of behavioral traits. Read both of the following articles from the web, and then complete the assignment below. · Do our genes make us popular? From Scientific American http://www.scientificamerican.com/article/popularity-genes/ · Minnesota Study of Twins Reared Apart, from the Minnesota Center for Twin and Family Research http://mctfr.psych.umn.edu/research/UM%20research.html Address the following questions in your essay: · What is most striking to you in the results presented in the two articles? · In the article on popularity, do you agree with the conclusion that there is a genetic basis to how popular people are? Explain why or why not. · In the twin studies, do you think that the behavioral similarities in identical twins raised apart from birth (like “the Jim Twins”) are due to inheritance? Explain why or why not. · Conclude by stating whether or not these two articles have changed the way that you think about genetics, and explain your answer.

OVERVIEW:

As we already know probiotics are microorganisms that provide us with health benefits when they are consumed. For this study healthy adults who have no previous history of probiotic consumption, any drugs, no vitamins or supplements and no special diet will be selected. To see the effect of probiotic on the gut microbiome, fecal samples of all participants will be collected and tested for the presence of any administered combination of microorganisms and any new microbial species that may have grew in the gut due to probiotic consumption. Fecal sampling will be done before probiotic consumption starts and will also be conducted throughout certain intervals throughout the study.

To see total anti-oxidative activity a linolenic acid test will be performed before the start of this study and during the determined intervals throughout the study.

All results at the end of the study will go through statistical analysis in order to determine if results are significant or not. Study will only be successful if there is change in the amount of oxidative stress before and after probiotic consumption .

If this probiotic formulation is effective gut microflora and total antioxidative activity will increase.

QUESTION:

Could you go into more detail of how you would do this analysis? How would you examine the population of the microbiota, and what parameters would you use to decide whether new microbial species were present?

I would add that you could see changes in composition that don't actually mean the appearence or dissappearence of a species (OTU). Do you have a plan to account for this?
