dominance–subordination

dominance–subordination

a form of social relationship within groups with a leader or dominant member who has priority of access to resources over other, subordinate members of the community. Among nonhuman animals, dominance–subordination relationships are highly organized in troops of baboons, in which dominant males have more access to food resources and mates than do subordinate males and all males often appear to have dominance over females. In hyena groups, the relationship is reversed, with males subordinate to females.
