46. Coevolution between Spiroplasma genes that kill sons and the nuclear genes of the fly that suppress son-killing would be an example of: A. The interspecific Red Queen B. The intraspecific/intergenic Red Queen C. Interspecific mutualistic coevolution D. Intraspecific mutualistic/intergenic coevolution E. Answers A & B are both correct EEMB2 Final Salmon Version: 0 Page: 13

47. If the son-killing Spiroplasma were killed by gene products coded by the fly-helping Wolbachia , but mutations in Spiroplasma could make it resistant to this killing, then coevolution between genes mediating killing and resistance would be an example of: 48. If the mitochondria evolved to produce the the son-killing phenotype of Spiroplasma , then coevolution between genes mediating killing and resistance would be an example of: 49. If the son-killing phenotype of Spiroplasma were suppressed by a combination of interacting gene products produced by the several nuclear genes of the fly and also by genes coded by Wolbachia , then coevolution between the genes suppressing son killing by Spiroplasma would be an example of: 50. Suppose that the fly had chromosomal sex determination with XX males and XY females. Genes on the Y chromosome would be selected to: A. Kill sons like Spiroplasma does B. Suppress son-killing by Spiroplasma C. Evolve mutualistically with other genes that suppress son-killing by Spiroplasma D. Answers B and C are both correct E. None of the above answers is correct EEMB2 Final Salmon Version: 0 Page: 14

    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.
