males in the lakes which have much more limited coloration on the tips of their their fins and tails. Females in the river, and in lakes B, C, and D, have a strong mating preference for mates with more colorful tails (green or red) or fins (red or blue). Females in lake-A have no mating preference for tail color but do prefer as mates males with more colorful fins. 91) The coloration pattern of males in the lakes and the river, irrespective the information from the phylogeny, supports the hypothesis that: A) Intersexual selection is stronger than intrasexual selection in the lakes B) Intersexual selection is weaker than intrasexual selection in the lakes C) The level of predation is weaker in the lakes D) The level of predation is weaker in the river E) None of these answers are correct 92) If females in the river had stronger preference for colored tails than females from all the species from all the lakes, then this pattern of female preference for tail color would indicate that the evolution of colored tails in the lakes is most likely explained by: (Lake-A) red-tailed blue-finned (Lake-C) red-tailed red-finned (Lake-D) green-tailed red-finned (Lake-B) green-tailed

93) Suppose that the sisters of males with brighter fin color (green, blue or red) had higher survival and produced more offspring over their lifetime, and that this pattern was also found when the sisters were reared by foster parents. This finding would most support which model for the evolution of males with colored fins: 94) Suppose that females from the river had a preference for fin color (green, blue, or red) that was weaker than that of females in all of the lakes. This pattern best supports the hypothesis that the trait “colored fins” evolved in the context of the: 95) If females from all the lakes and from the river had no mating preference for males with colored fins, then this trait probably evolved via A) Intersexual selection B) Intrasexual selection C) Female preference for colored fins D) Good genes model E) Both answers B & D are correct. ___________________________________________________________________________________

Use the following information for the next 10 questions (until you see a solid line): In most plants, mitochondria and chloroplasts are only passed on to the next generation through the egg and not through the pollen. This “passed-on-only-through the-egg” or “maternal-vertical” transmission pattern also applies to some intracellular bacteria. Because of maternal-vertical transmission, pollen is an evolutionarily “dead end” with respect to the fitness of mitochondria and chloroplasts. Some mitochondria have evolved pollen-killing phenotypes that convert hermaphroditic plants species (in which each flower produces pollen and eggs) into species that have female (all pollen killed) and hermaphroditic plants (pollen not killed).

    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.
