1) Why do males often compete for access to females more than females compete for access to males

1. 1) Why do males often compete for access to females more than females compete for access to males • A) males invest less in reproduction • B) access to females limits male reproduction, but not the reverse • C) both of the above

2. 2) Fisherian runaway • A) means that selection favors faster running • B) depends on a genetic correlation between preference and trait genes • C) is a “good genes” explanation for why females have mating preferences • D) means that daughters express the same mating preferences as their brothers • E) applies only to birds

3. 3) “good genes” • A) is shorthand for the selection on female mating preferences that result in attractive sons, but not higher viability • B) is the idea that male display traits reveal something about male genetic quality • C) has very little data to support it

4. 4) Sexual selection in plants • A) makes basically the same predictions as in animals • B) predicts floral investment in displays is primarily repaid via export of pollen • C) depends upon animal pollinators, not wind pollinators • D) all of the above

5. 5) Sperm competition • A) only occurs in species in which females mate with multiple males • B) favors infanticide • C) can favor traits such as large testis, large numbers of sperm, and modifications of male genitalia • D) all of the above • E) A and C above, but not B
