mRNA transcripts that differentiate between personalities in a zebrafish population are transferrable to other fish populations. Log10-transformed copy number of indicated mRNA transcripts grouped by different behaviour phenotypes in (a) S. salar (b) D. labrax. Whiskers show standard deviation and different lower-case letters indicate significantly different groups (p < 0.001, ANOVA, Tukey-HSD Multiple pair-wise comparisons, 95% confidence level). Principle Component Analysis (PCA) of individual brain with the expression levels of animal personality-specific mRNA transcripts as original variables for (c) S. salar (d) D. labrax. The percentage of the variation explained by PC1/2 is shown in coordinates; Dots represent individual brains coloured by behaviour profile, the ellipse represents the core area with the default 68% confidence interval; The arrow represents the original variable, where the direction represents the correlation between the original variable and the PC, and the length represents the contribution of the original variables to the PC. Colour scheme for different behaviour phenotypes is consistent within each species
