Essay Question 1 – you need to either answer this question or SKIP this question by answering Essay Option 2. Think about the last time you were deeply focused on something — studying, scrolling your phone, watching a game — and completely missed something happening right in front of you. Now imagine that same experience happening to someone who just witnessed a crime. Using concepts from at least two of the chapters you have read this semester, write an essay that explains why eyewitness testimony may be less reliable than it appears. In your essay, you should identify the relevant psychological concepts by name, explain how they work, and use them to build a clear argument about why a witness’s account of an event might be incomplete or inaccurate — even when that witness is being completely honest. Support your argument with specific examples, either from the readings or from your own reasoning. A strong response will go beyond simply defining terms and will instead show how the concepts you chose work together to affect what a person sees, remembers, and reports.

Choose the role(s) testosterone play regulating differentiation of the developing male embryo. (Choose all correct)

Thomson argues that killing of persons/humans is impermissible but argues for the permissibility of abortion because 

Feinberg argues that killing a human is wrong but killing is a fetus is permissible because  

Which of the following is a thought experiment that Thomson uses to make her argument?

The following question will only be shown in the actual exam, so it is important to collect all the data/information before submitting/disconnecting from your exam. NOTE: The essay question will be graded separately and it is worth 20 points. Complete your work on a blank piece of paper. You will have 30 minutes after you finish your test to finish and submit all the answers for this question and the calculations to the indicated multiple choice questions to the “Exam 2 Part 2” assignment on the “Exams” link. Submit BOTH SIDES of each paper as a single PDF file (preferred) or jpeg file. A population of fish called the founder generation is introduced into the freshwater lake of Karu. The population consists of 200 Blue (BB) individuals, 400 Green (Bb) individuals, and 400 Yellow (bb) individuals. Assume the population mates randomly, the genotypes are selectively neutral, and mutation and migration are negligible. Questions: (a) What are the frequencies of alleles B and b in the founder generation? Show your calculations. (4 points). Frequency of allele B = __________________ Frequency of allele b = __________________ (b) Calculate p2, 2pq, q2 and the expected number of BB, Bb, and bb individuals in the population, assuming Hardy-Weinberg equilibrium (HWE). Show your calculations. Hint: use the p and q values you found above. (6 points). p2 = 2pq = q2 = Expected number Blue (BB) = Expected number Green (Bb) = Expected number Yellow (bb) = Is the founder generation at Hardy-Weinberg equilibrium? Find ALL the values needed to complete the table below and write them down on your sheet. Last row can be left as fractions. The χ2 value was kindly provided by Dr. Holechek’s Grad TA. Hint: The expected frequencies and expected values are the ones you estimated in (b). (4 points, 0.25 per square). Observed and expected genotype counts by phenotype Phenotype Blue Green Yellow Total Genotype BB Bb bb – Observed 200 400 400 Observed Frequency Expected Frequency Expected (O − E)2 / E χ2 = 27.77   Use the provided χ2 table below to determine whether this population is in HWE at the B locus. (c) What is the P value that corresponds to this Chi-square (χ2) value? (1 point). ______________ (d) Is the population in HWE? Briefly explain your answer. (2 points). ___________________________________________ (e) Mention 3 reasons why most populations are not in Hardy-Weinberg equilibrium. (3 points). 1. 2. 3.
