Frequency-Dependent Selection

Problem 3 - Find the mean fitness given a specific value of A1.

In problem 2 you determined that p = 1/2 is an equilibrium, what is the mean fitness at this equilibrium?

Recall that

and

w11 = 1 - cp,

w12 = 1 - ½cp,

w22 = 1 - c + cp

 

 

  

A.

 

B.

 

 1

C.

 

 1 - 3c

D.

 

 0
E. c
F.

Problem 4 - Describe the graph of the function representing the equilibrium value of A1.
