Table 3. Assessment of “forager-like” or “nurse-like” characteristics of the gene lists from Table 1, using the 100 “behavior marker” genes: Correlational analyses.  Correlation analysis was performed on forager-nurse brain expression ratios for the behavior marker genes and expression ratios for the same genes from the gene lists generated in Experiment 2.  Above diagonal: correlation (r) and significance (p, in parentheses) for comparisons of the behavior marker genes; regressions significant at p < 0.001 are in bold. Below diagonal: correlation (r) for all genes; all positive and negative correlations were highly significant (p < 10^-6) except Mn vs. cGMP. Gene expression data for QMP were taken from ref. 15.
