10. Suppose that green-winged babbler is a member of a clade of birds that lack head plumes (except for the green-winged babbler), including species closer to the clade’s root. Experiments show that female attraction to a head plume is a synapomorphy for the clade, but that female preference for this trait is similar in all species. This finding would best support the hypothesis that the head plume evolved via the: A. sensory exploitation model B. sexy sons model C. sexual conflict model D. material benefits model E. good genes model Use the following information for the next 5 questions (until you see a solid line): A population of asexual flowers has four genetic variants (genotypes, Y, G, W and R) that code for flower colors that are yellow (Y), green (G), white (W) or red (R). The frequencies of the four types in the spring of 2011 (just before the seeds begin to germinate) were: 100 Y, 200 G, 200 W, and 500 R. The frequencies in 2012 (measured at the same time as 2011) were: 200 Y, 200 G, 100 W, and 1500 R. 11. The estimated Darwinian fitness of the genotype with white ( W ) flowers is: A. 0.25 B. 0.5 C. 1.0 D. 1.5 E. None of these answer is correct 12. The average fitness of the population is: (hint: this can be calculated without calculating the fitness of all of the genotypes ): A. 0.25 B. 0.5 C. 1.0 D. 1.5 E. None of these answer is correct 13. The change in the gene pool frequency of the R genotype after one generation of natural selection was: A. 0.0 B. 0.1 C. -0.1 D. 0.25 E. None of these answers is correct 14. The fitness of the G genotype indicates that: A. It is replacing itself and therefore selectively neutral B. It is increasing in frequency in the genotype pool C. It codes for the second best gene transport machine D. It will eventually predominate in the genotype pool E. None of these answers is correct EEMB2 Final Salmon Version: 0 Page: 4

15. In general, which statement summarizes the process of evolution by natural selection: A. Genotypes with higher survival are the fittest B. Genotypes with higher fecundity are the fittest C. Genes that code for phenotypes that leave more offspring in the next generation accumulate in the gene pool D. Phenotypes that code for genotypes that are better gene transport machines are favored by natural selection E. Both answers (A) and (B) are correct Use the following information for the next 5 questions (until you see a solid line): John Doe is interested in the hereditary basis of susceptibility to a form of a common cold virus. He collected a random sample of people and genotyped them at the D locus for two alleles: D High , which he hypothesizes increases susceptibility to the virus, and D Normal . The sample is tabulated below as the entire sample and also the subset of individuals who had no antibodies to the virus (uninfected).
