Frequency-Dependent Selection

Problem 2- Find the values of A1 that are roots for a given equation describing the equilibrium values of A1.

Intuition tells us that p = 1 is an equilibrium because it corresponds to the fixation of allele A1; in other words, in the absence of genetic variation and mutation all individuals will be A1A1 for all time. Verify that p = 1 is a root of ,

f (p) = 2p3 - 7p2 + 7p -2,

and use this fact to find the remaining two roots. What is the sum of the remaining two roots?
