18. Focusing on each data set separately to calculate gene frequencies: A. The infected sample conforms to the Hardy-Weinberg equilibrium model B. The entire sample does not conform to the Hardy-Weinberg equilibrium model C. The entire sample conforms to the Hardy-Weinberg equilibrium model D. Both A and C are correct E. None of these answers is correct 19. In the uninfected sample, John Doe’s null model would predict: 20. Application of the scientific method to John Doe’s results leads to what conclusions: EEMB2 Final Salmon Version: 0 Page: 6

Use the following information to answer the following 5 questions (until you see a solid line): Genes in the genome sometimes become duplicated due to DNA replication errors. One type of gene duplication is a tandem repeat, in which the new copy of a gene is located immediately next to the original copy. Additional copies of the gene can be produced in the same way to produce tandem repeats longer than two copies. DNA replication errors can also delete one or more copies of previously duplicated genes. Jane Doe decides to use the copy number of 10 genes to construct a phylogenetic tree for 5 bird species (A, B, C, D, and E) and a more distantly related reptile species (T) 21. A synapomorphy for all the birds is: 22. Species forming a polytomy are: A. species-D and species-A B. species-C, species-B, and species-D C. species-C and species-E D. there are no polytomies E. all species except the outgroup 23. According to this phylogenetic tree, the reptile’s closest relative is: EEMB2 Final Salmon Version: 0 Page: 7

    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.
