10. If the same 10 genes were used to construct a phylogeny for 5 different and more distantly related taxa and all taxa had a different copy number for all of the genes, this would be equivalent to what phenomenon with DNA sequence data: A. saturation B. reversal C. a root D. a synapomorphy E. None of these answers is correct Use the information below for the next 5 questions (until you see a bar beneath the question) A epidemiologist traces the fate of 500 newborn feral cats during an outbreak of a viral disease. 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: 12. The relative fitness of the least fit genotype(s) is: EEMB 2 Final Ivory Version: 0 Page: 4

13. The proportion of the G 1 allele in the newborns is: 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 ): 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: 17. The average fitness of the population is: (hint: this can be calculated without calculating the fitness of all of the genotypes ): 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

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
