Suppose That in the Hawk-Dove Game Discussed in Problem 8

question 22

Multiple Choice

Suppose that in the Hawk-Dove game discussed in Problem 8, the payoff to each player is -9 if both play Hawk. If both play Dove, the payoff to each player is 5, and if one plays Hawk and the other plays Dove, the one that plays Hawk gets a payoff of 9 and the one that plays Dove gets 0. In equilibrium, we would expect hawks and doves to do equally well. This happens when the proportion of the total population that plays Hawk is

• A) .31.
• B) .15.
• C) .08.
• D) .65.
• E) 1.

Definitions:

Fixed Genetic Locus

A specific location on a chromosome where the genetic variation has become identical across all members of a population due to evolutionary processes.

Allele

A variant of a gene that occurs due to mutation and is located at an identical location on a chromosome, representing one of two or more possible versions.

Genetic Drift

A mechanism of evolution that results in the change of the frequency of alleles in a population due to random sampling of organisms.

Evolution

The process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
