Which of the following can be considered examples of trait variation being maintained by frequency-dependent selection? 1)An aggressive strategy never works better than a non-aggressive strategy does,even if virtually 0% of individuals use the aggressive strategy 2)An aggressive strategy works better than a non-aggressive strategy does,but only if less than 10% of individuals use the aggressive strategy 3)An aggressive strategy works better than a non-aggressive strategy does,but only if less than 70% of individuals use the aggressive strategy.

Recall the "hawk-dove game," which simulates competition between individuals.Which of the following statements can accurately describe the features of this game? 1)When there are few hawks in the population,they do better than doves,because the hawks always win in hawk-dove competition 2)When there are few doves in the population,they do better than hawks,because of the heavy costs incurred by hawks in competing with each other 3)Because hawks always defeat doves,the doves eventually go extinct 4)Doves lose to hawks individually,but a team of doves defeats a team of hawks.

Below are several statements about comparisons between countries in the average levels of personality traits as measured by self-report.Which of these can be considered accurate? 1)There are very large differences between countries 2)The differences between countries correspond closely to national stereotypes 3)The differences might be somewhat underestimated,because people's self-reports are based on comparisons with people in their own country 4)Some differences might be due to differing tendencies to give socially desirable responses to self-report questionnaires.

Recall the study of Trinidadian guppies (a species of fish)by O'Steen et al. (2002).Which of the following accurately describes the findings of that study?

Recall that interpretations of the adaptive trade-offs of Honesty-Humility have considered age and sex differences.Which of the following statements is accurate?

Which of the following can be considered examples of trait variation being maintained by a fluctuating optimum level of a characteristic? 1)A rounder body shape is favored in cold climates,but a longer body shape is favored in hot climates 2)Rapid growth is favored if there is much vegetation,but slow growth is favored if there is little vegetation 3)A cautious style is favored if there are many predators,but a bolder style is favored if there are few predators.
