| Abstract: | The male mice of two strains with experience of 2 or 10 defeats in intermale agonistic confrontations significantly differ in pattern of submissive behavior (balance of upright and sideways defensive postures, withdrawal, freezing, "on the back" posture). In mice with experience of 20 defeats genetic differences have not been found. The acquisition of consequent experience of defeats does not change the pattern of CBA mice submissive behavior, but significantly increases the share of immobile submissive postures in behavior of C57BL mice. Among submissive males of C57BL strain animals with more active strategy of behavior keep capability for aggressive response to weaker partner. The influence of genotype and previous social contact experience on formation of adaptive in experimental situation strategy of submissive behavior is discussed. |
