Sexually dimorphic expression. (A) The proportion of sexually dimorphic expression in each tissue versus total sexual dimorphism. The ratio of female- to male-biased expression is provided (female:male). All ratios deviate significantly from equality (Chi-squared test; P < 0.05). (B) Hierarchical clustering of probes among tissues and sex with Euclidean Distance; female (red), male (blue). Branch support was estimated with 10,000 bootstrapped replicates. Expression enrichment against carcass for the (C) ovary and (D) testis. Significant gonad enrichment is highlighted in dark grey (ANOVA; M > 2; Q < 0.05). Inset figures show the proportion of gonad enrichment which is also sexually dimorphic in whole-body samples, i.e. 51% female-biased (dark red); 7% male-biased expression (dark blue).
