父母通过遗传和非遗传机制影响后代的攻击性，尽管对后者的了解较少。为了检测父母对后代的潜在非遗传影响，我们交叉培养了高度攻击性和双亲加州小鼠(Permyscus CalforNicus)和攻击性较弱、亲本较少的白足小鼠(Permyscus Leucopus)。以每个物种内寄养的动物作为对照。我们研究了寄养父母的行为与寄养的雄性后代在居民-入侵者(R-I)和中性竞技场攻击测试中的攻击性之间的联系。当物种和寄养群体结合在一起时，后代的R-I攻击性与父亲花在取回幼崽上的时间呈正相关。相比之下，在中性环境中的攻击性与母亲行为的综合得分呈负相关。我们讨论了我们关于父系取回的发现如何解释先前报道的交叉养育对男性攻击性的影响。
Parents influence offspring aggression through genetic and non-genetic mechanisms, although the latter are less well understood. To examine potential non-genetic effects of parents on offspring, we cross-fostered the highly aggressive and biparental California mouse (Peromyscus californicus) and the less aggressive, less parental white-footed mouse (Peromyscus leucopus). In-fostered animals within each species were used as controls. We examined associations between the foster parents' behavior and aggression of the fostered male offspring in resident-intruder (R-I) and neutral arena aggression tests. When both species and fostering groups were combined, R-I aggression of offspring was positively associated with paternal time spent retrieving pups. In contrast, aggression in a neutral arena was negatively associated with a composite score of maternal behavior. We discuss how our findings regarding paternal retrievals may explain previously reported effects of cross-fostering on male aggression.
