Unformatted text preview: The cats vary with respect to the alleles that they carry at a gene locus that influences the immune system. The fate of the cats in the sample is described below You can use our discrete-generation model of natural selection as an approximation to analyze this data and assume the population is outbred. 11. The Darwinian fitness of the fittest genotype is: A. 2 B. 4 C. 8 D. 0 .25 E. 1.0 12. The relative fitness of the least fit genotype(s) is: A. 1 B. 2 C. 0.1 D. 0.25 E. 0.5 EEMB 2 Final Ivory Version: 0 Page: 4 13. The proportion of the G 1 allele in the newborns is: A. 0.1 B. 0.2 C. 0.5 D. 0.8 E. 0.9 14. The relative fitness of the G 1 allele is: A. 0.25 B. 0.40 C. 0.50 D. 0.75 E. none of these answers 15. Rounding mean fitness to a single decimal place (i.e., 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9) , the expected proportion of the G 1 allele next generation is ( hint: some of the following information may be helpful: 0.25*0.4=0.1, 0.8*0.25=0.2, .1/.3 = .33, .2/.3 = .67, 4/5 = = 0.8, and 1/4 = .25 ): A. 0.15 B. 0.33 C. 0.67 D. 0.8 E. none of these answers 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. 16. 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 17. 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 EEMB 2 Final Ivory Version: 0 Page: 5 18. 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 19. 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 20. 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): A bird species (the green-winged babbler) has two traits that you suspect may influence sexual...
