lecture 11

Question 1

what is game theory?

Answer 1

asks the questions: what behavioural strategy should individuals adapt to maximize their individual fiteness and does the best strategy depend on the strategy of other individuals

Question 2

what is evolutionary stable strategy?

Answer 2

a behavioural strategy that is resistant to invasion and most likely to be maintained by natural selection

Question 3

what is simple vs frequency-dependent selection?

Answer 3

an individuals fitness depends on the behaviour (and the frequency of the behaviour) of others

Question 4

what is frequency dependent selection?

Answer 4

occurs when the fitness of an individual depends on the relative frequency of other phenotypes in the population

Question 5

what is positive frequency dependent selection?

Answer 5

majority advantage (majority phenotype wins)

Question 6

what is negative frequency dependent selection?

Answer 6

minority advantage, promotes genotypic and phenotypic diversity, some combination of phenotypes
