Unformatted text preview: EEMB 129 Midterm II Name____________________________ 2008 Perm #___________________________ Read each question carefully before you answer it. Make sure that you show your work. 1. (10 pts). In a large population of range cattle, the following ratios are observed: 49 percent red (RR), 42 percent purple (Rr) and 9 percent blue (rr). a) What are the allele frequencies? b) Is the population in HardyWeinberg Equilibrium? Show your work. c) Assuming no evolutionary forces are acting on this population, what will be the percentages of each phenotype in the next generation? 2. (8 pts) You have genotyped a mother and her offspring at four unlinked microsatellite loci and obtained the following results. Locus 1 Locus 2 Locus 3 Locus 4 Mother A 1 A 4 B 2 B 7 C 5 C 9 D 2 D 4 Offspring A 1 A 2 B 7 B 9 C 9 C 10 D 2 D 4 Males: 1 A 1 A 7 B 3 B 4 C 6 C 7 D 3 D 4 2 A 2 A 9 B 5 B 9 C 1 C 9 D 1 D 6 3 A 3 A 4 B 2 B 4 C 2 C 3 D 6 D 8 4 A 2 A 8 B 2 B 9 C 5 C 10 D 4 D 5 5 A 6 A 7 B 8 B 9 C 5 C 9 D 2 D 4 6 A 2 A 4 B 1 B 3 C 3 C 10 D 4 D 8 a) Which, if any, of the males could be the father of the offspring? (4 pts) b) If there are 10 alleles at each locus and all alleles are of equal frequency, then what is the probability of...
