Key genes of the perturbed pathways. Differentially-expressed genes (T test p ≤ 0.05) between wild and domesticated embryos and identified as essential for the pathways perturbed between pure stocks (Table 1). Genes are plotted according to log₂ fold change (domesticated vs. wild) and −log₁₀ p value (T test), and color-coded by biological function. The list of plotted genes and values are included in Table S4 (see Additional file 1: Table S4)
