In the context of the runaway sexual selection hypothesis, what role does female mate choice play in the evolution of exaggerated traits in males? Females ignore males with exaggerated traits in favor of other factors such as resources Females display exaggerated traits themselves to attract males with similar traits Females have no preference for males with exaggerated traits Females actively select mates with these traits, leading to their exaggerated development

Phalaropes are shore birds with brightly colored females and dull colored males. Females are larger than males and compete with each other for access to males. Considering sexual selection theory, select the idea(s) below that seem(s) most plausible in light of the pattern of sexual dimorphism? Pick all that apply This is a picture of a brightly colored female: O Females incubate eggs and care for the young. Males incubate eggs and care for the young Males are choosy. males are not choosy
Intrasexual selection involves competition among one sex (typically males) for mating access to the other sex. Intersexual selection involves mate choice in which individuals from one sex (typically females) choose their mates from among individuals of the other sex. Imagine a group of males that is engaged in agonistic behavior, from which Male A emerges triumphant. Now imagine a female that is assessing all of the males that were involved in the fights, and chooses Male A. Explain why this situation shows how intrasexual and intersexual selection pressures are likely both at play in the trait selection.
In seahorses, males incubate and care for offspring. Thus, the males are more likely to be tied up in reproduction at any point in time relative to females. Which sex do you predict will be the choosey sex in this species and why? Males -- because fewer are available to mate Males – because male-male competition is incredibly strong Females – because sperm are cheap to produce Female – because the operational sex ratio is biased in their favor The sperm of chimpanzees have faster swimming speeds than those of gorillas. Based on what you know about sperm competition, what would you predict about differences between these two species in female re-mating frequency and sperm viability? In chimps, females mate only once and sperm are viable for only a day In chimps, females mate multiply and sperm live for a long time In chimps, females mate only one, and sperm live for a long time In chimps, females mate multiply, and sperm live for only a day Which of the following sexual traits is…
Assume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.
why do females have a greater disadvantage compared to males concerning sexual reproduction? How has this difference between the sex shape sexual selection in general? Choose one form of communication and explain how it is used by competing sex is attracting a mate.
How might the following findings be understood in terms of the adaptive value of female mate preferences? Deep-voiced men have more children in a traditional hunter- gatherer culture, the Hazda of Tanzania. Taller men are more likely to be chosen in speed-dating competitions than their shorter rivals (Belot and Fancesconi 2006) and are more likely to be chosen as sperm donors by women in California (Egan 2006). Images of men with slightly bloodshot eyes are judged less attractive than photographs of the same men in which the whites of the eyes are clear (Provine et al. 2011).

Explain how sexual selection might lead to a)sexual dimorphism and b) members of one sex (usually male) having traits that do not enhance their survival
The good genes model of sexual selection is a popular hypothesis for mate choice. What is an underlying flaw with the hypothesis that must be explained?
Define sexual selection and describe an example of intersexual and intrasexual sexual selection in animals. Be sure to detail what trait(s) is/are being sexually selected.
Would you expect sexual selection to increase or decrease adaptation of a population to its environment? Do the pleiotropic effects and good genes mechanism for the evolution of female preferences differ in their implications for adaptation to the environment?
In seahorses, males incubate and care for offspring. Thus, the males are more likely to be tied up in reproduction at any point in time relative to females. Which sex do you predict will be the choosey sex in this species and why? Males -- because fewer are available to mate Males – because male-male competition is incredibly strong Females – because sperm are cheap to produce Female – because the operational sex ratio is biased in their favor
Which of the following is NOT an example of sexual selection in the wild? * Peacocks showing off bright feathers to attract the peahens. Newts camouflaging in their environment so predators can't see them. Frogs singing loud songs to attract a mate. Rams butting heads and fighting to gain access to the females.
