Dominance is an attribute of the pattern of repeated, agonistic interactions between two individuals, characterized by a consistent outcome in favour of the same dyad member and a default yielding response of its opponent rather than escalation. The status of the consistent winner is dominant and that of the loser subordinate. (Drews, Carlos. (1993). The Concept and Definition of Dominance in Animal Behaviour. Behaviour. 125. 283-313. 10.1163/156853993X00290.)
