76) If the receptor-X was found to rapidly evolve at the same rate in mountain and lowland populations, then these data would best support the operation 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 77) If the receptor-X was found to rapidly evolve, but only in lowland populations, then these data would best support the operation of :

78) Suppose that comparative genomic data indicated that sperm first started using receptor-X as a binding site about 10 million years ago. If, in mountain populations, the gene coding for the protein that binds sperm to receptor-X was found to rapidly evolve between 9-10 million years ago, but during the last 9 million years to have evolved relatively slowly, then this pattern of evolution best supports the operation of: 79) If the receptor X was found to rapidly and continuously evolve in both mountain and lowland populations, but faster in the lowlands, then these data would best support the operation of : 80) If in some lowland locations the virus was a generalist that infected many different species of frogs (entering the eggs through s similar receptor in all the species of frogs), and other lowland locations the virus only infected the blue-legged frog, then you would expect: A) faster evolution of receptor-X where the virus was a specialist B) faster evolution of receptor-X where the virus was a generalist C) faster evolution of the sperm binding protein where the virus was a specialist D) no difference in the rate of evolution of receptor-X where the virus was a generalist or specialist E) Answers A & C are both correct

Use the following information for the next 5 questions (until you see a solid line): A tropical fish species (species-T) has two traits that you suspect may influence sexual selection: a bright red spot on the tail and bright blue body coloration. Females lack the color spot and their body coloration is a cryptic brown. Females have a solicitation display that they use to signal males that they are ready to mate with them. In controlled experiments, males with bigger red tail-spots received more solicitation displays from females, and males with brighter blue body coloration were better able to defend their mating territories from intruders and they received more solicitation displays from females.

    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.
