(Solution Download) The per capita production of each type is reduced by


The per capita production of each type is reduced by a factor of 1 - p by a factor of 1 - p, so that the per capita production of type a is 2(1 - p). This is a case where a large proportion of type a reduces the production of both types. Will type a take over?
The model of selection includes no interaction between bacterial types a and b (the per capita production of each type is a constant). Write a pair of differential equations for a and b with the following forms for the per capita production, and derive an equation for the fraction p of type a. Assume that the basic per capita production for type a is ? = 2, and that for type b is ? =1.5.
