We saw in our hawk/dove game that a polymorphic ESS exists with a population of 70 percent hawks and 30 percent doves.

We saw in our hawk/dove game that a polymorphic ESS exists with a population of 70 percent hawks and 30 percent doves. But we could consider a mutant phenotype in this game that acts as a hawk 70 percent of the time and a dove 30 percent of the time. Show that this phenotype is a monomorphic ESS—it cannot be successfully invaded by either hawks or doves
