Heritability of aggression following social evaluation
95
relative to neutral feedback showed similar influences of shared environment (C=8%) and relatively less influence of genetics (A=10%, Table 2), and was best described by a CE-model (Table S1). Aggression following neutral relative to positive social feedback showed no influence of shared environment (C=0%) and was most influenced by unique environment (90%, see Table 2 and Table S1).
