86) Coevolution between the bacteria and the invertebrate host 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 87) If a mitochondrial gene evolved that weakened males (but not females) and thereby enhanced the ability of the bacteria to kill males, this mutation would influence: 88) Suppose that a gene on the Y chromosome evolved that protected males from the male-killing phenotype of the bacteria. This would be an example of one step of: 89) Suppose the endosymbiont bacteria is absent and that a gene on the Y chromosome evolved to produce a gene product that attached to a gene on the X chromosome. This attachment disrupted the X chromosome’s chromatin structure during gamete formation so that in the next generation females died as embryos. This would be expected to lead to:

______________________________________________________________________________________ 90) Suppose that an autosomal mutation coded for a new behavior in lions: it caused the male lion expressing the mutation to invariably die while taking the lead in dangerous male-male fights that occur during competition for mates. This behavior increases the ability of his brother to secure a pride (group) of females for reproduction. Without help from a brother, an average male lion produces (over his entire lifetime) an average of 2 offspring. With help from a brother, a male produces an average of 5 offspring. The mutation: A) increases the Darwinian fitness of its carrier B) decreases the Darwinian fitness of its carrier C) is favored by kin selection D) is disfavored by kin selection E) Answers B and D are both correct

Use the following information for the next 5 questions (until you see a solid line): Joe Schmoe discovers a group of 4 isolated alpine lakes (named A, B, C, and D). Each lake has a unique species of fish. Joe uses molecular data to construct a phylogeny of the fish (see below). All females have drab and mottled coloration that makes them hard for predators to see, but the males can be more brightly colored and conspicuous. The coloration pattern of the males was used to name the species. All the species are derived from a single species in a nearby river in which males and females both have drab tails and fins but the males from the river have bright colors spots on the surface of their bodies and are far more conspicuous then the males in the lakes which have much more limited coloration on the tips of their their fins and tails. Females in

What students are saying

    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.
