Effects of genotype on maternal aggression in CRF2 KO and WT mice. Bars represent non-transformed mean differences ± SEM within each genotype. Statistics represent transformed data (see Results). A) Mean latency to first attack was significantly longer in CRF2 KO dams relative to WT dams (ANOVA). B) Mean number of attacks was not significantly altered in CRF2 KO dams relative to WT dams (ANOVA). C) Mean total time aggressive was not significantly altered in CRF2 KO dams relative to WT dams (ANOVA). D) mean time to retrieve first and fourth pup was not significantly altered in CRF2 KO dams relative to WT (ANOVA). * p<0.05.
