Study Questions for Chapter 10: Mate Choice
1. Why
do females choose and males display (in most animals)?
2. What
is the male's extended phenotype, and give an example
of an experimental test of the role of the male's extended
phenotype in affecting female choice. Why is it necessary
to do such experiments?
3. What are two
assumptions of the model of runaway process? What is a key
prediction of the theory of sexual selection by runaway process? Describe evidence
supporting the key prediction.
4. How
do these two assumptions differ from indicator models of female choice?
5. Describe why a comparative
test of the parasite/sexual selection hypothesis that
compares different species is less powerful than an experimental
test within a single species?
6. Do
females forage for mates?
7. Define
direct versus indirect benefits of mate choice. Give an
example of each (or one example with both).
8.
Why should you avoid using cologne or perfume if you are
searching for the true love of your life?
9. What is female copying?
10. Outline the null hypotheses, and alternative hypotheses
for all the relevant models of mate choice.
