FIGURE 4.

Anxiety-related hyponeophagia test at P27 and P37. Female C57BL/6N and DBA/2 mice showed an increased latency to drink the diluted milk compared to male mice in both trials 1 and 2 at P27 (A) but not at P37 (B). At both P27 and P37, no strain difference was found in the latency to drink the diluted milk. The green asterisk indicates a significant difference between males and females. Two-way ANOVA followed by Tukey post hoc test,*p ≤ 0.05, **p ≤ 0.01. Blue and red dots represent males and females, respectively. Error bars indicate the standard error of the mean (SEM).
