Abstract Reciprocal cross‐fostering of mice was carried out between an inbred strain (C57 BL/6) in which the female showed a particular form of aggression toward lactating female intruders, and a strain (C3H/He) which proved to lack totally this type of attack. In adulthood, cross‐fostered females of the 2 strains and their controls were submitted to a series of aggression tests. They encountered in the test situation either a strange lactating female of their own strain or one of the foster strain. No differences in aggression measures were found between cross‐fostered animals and controls, indicating that experiential factors (viz., cross‐fostering) were without effect.
