  A new evolutionary solution to Prisoner Dilemma situations is proposed in
this paper. A specific genetic code may have different phenotypes, meaning
different strategies for different individuals carrying that gene. This means
that, under the right parameters, it is a good evolutionary solution to create
two types of phenotypes with different strategies, here called as leaders and
servants. In this solution, servants always cooperate with the leaders and
leaders never do with the servants. Inside the same class, the usual strategies
apply. Possible applications of this solution are discussed.
