FIGURE 7.

Association between methylation levels at position –1383 and the likelihood of dogs to approach the experimenter in an appeasing way. Males approaching the experimenter in an appeasing way had lower methylation levels than males who did not, while the opposite was true for female dogs. Horizontal bars represent medians, the bottom and the top of the boxes represent the lower and the upper quartiles, respectively, whiskers represent the interquartile range and filled circles represent outliers.
