Because our hypothesis is that the duplication increases gene expression and thus alters behavior, we also examined the relationship between the duplication and Glo1 expression in the amygdala (Figure 4C; p<0.000001) and the relationship between Glo1 expression in the amygdala and anxiety-like behavior (Figure 4D; p = 0.0012). This evidence concerns the gene GLO1 and Anxiety.
