Visual representation of heritability of genes differentially expressed between crosses in control (graphs on top) and stress (graphs on bottom) states. Heritability was plotted for both reciprocal hybrids; W♀ x D♂ (on the left) and D♀ x W♂ (on the right). α > 0 / α < 0 is characteristic of genes that are down/up regulated in domesticated compared to wild fish and − 0.5 < δ/α < 0.5 corresponds to additivity, −1.5 < δ/α < −0.5 to wild dominance, 0.5 < δ/α < 1.5 to domesticated dominance, and if δ/α falls outside the interval − 1.5-1.5, then this suggests over-dominance of the expression of the transcripts studied
