The fоllоwing questiоn will only be shown in the аctuаl exаm, 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 individuals, Bb individuals, and bb individuals in the population, assuming that the population is in 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 X2 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). Image Long Description A table with a black border contains rows and columns with text and numbers. The top row shows column headers: "Phenotype", "Blue", "Green", "Yellow", and "Total". The leftmost column contains row labels: "Genotype", "Observed", "Obs. Frequency", "Exp. Frequency", "Expected", and a mathematical expression "(O - E)²/E". The table shows "BB" under Blue, "Bb" under Green, and "bb" under Yellow in the Genotype row. In the Observed row, the numbers 200, 400, and 400 appear under Blue, Green, and Yellow respectively. Most cells in the table are empty or gray. In the bottom right corner, the text "X² = 27.77" is visible. 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. Image Long Description A table with a blue header row and white data rows. The header shows "Probability (P) Value" across the top with columns containing the values 0.99, 0.975, 0.95, 0.90, 0.10, 0.05, 0.025, and 0.01. The leftmost column is labeled "k" and contains numbers 1 through 10. The table contains numerical data arranged in a grid format, with each row corresponding to a k value and each column corresponding to a probability value. All numbers in the data portion are decimal values ranging from 0.000 to 23.21. Show both sides of each of the papers you used to the camera before submitting and exiting this part of the Exam. Do not forget to show your work for your questions on the scratch papers. You have up to 30 minutes to complete the essay question and submit your calculations and essay through Exam 2 Part 2.
Cаlculаte the Fixаtiоn index in the Subpоpulatiоn relative to the Total population based on the information provided. Image Long Description A mathematical equation. On the left side is "F_ST =" and on the right side is a fraction with "2pq - H" in the numerator and "2pq" in the denominator. All text appears in black on a white background. Image Long Description A table with a black header row containing three columns labeled "AA", "Aa", and "aa" in white text. Below are two rows of data: "Pop. 1" in the left column with green numbers 0.54, 0.20, and 0.26 across the three columns, and "Pop. 2" in the left column with green numbers 0.16, 0.40, and 0.44 across the three columns. The table has alternating light gray and white row backgrounds. Select the right answer and show your work on your scratch paper for credit.
