The Evolution of Social Dominance

A difference in dominance rank is an often-usedcue to resolve con icts between two animals without escalated Ž ghts. At the group level, adherence to a dominance convention efŽ ciently reduces the costs associatedwith con icts, but from an individual’s point of view, it is difŽ cult to explainwhy a low ranking individualshould accept its subordinatestatus. This is especially true if, as sugge...

Balanced Polymorphisms and the Evolution of Dominance.

We explore the evolution of dominance at polymorphisms maintained either by overdominant selection or by migration-selection balance. At such balanced polymorphisms, heterozygotes remain at appreciable frequencies over long periods of time, allowing extensive modification of dominance to occur. The strength of selection favoring a modifier of dominance is roughly proportional to the probability...
