The inheritance of agonistic behavior in male mice: A diallel analysis

The diallel cross genetic design was employed to determine the pattern of inheritance of male‐male agonistic behavior in laboratory mice. The results indicated strong strain differences in agonistic behaviors and strain ranks that replicated previous findings. The genetic analysis showed the presence of additive and nondirectional dominance effects on the behaviors measured. This pattern has been characterized as indicating the action of stabilizing selection and indicates that the trait has not been under directional selection.
