Principal component analysis (PCA). The first PC (PC1) and second PC (PC2) explained 34.5 and 17.9% of the variances, respectively. The loading components are shown in Table S2. The transcripts with loading component values larger than 0.75 and 0.70 for PC1 and PC2, respectively, are shown in the figure. The asterisks indicate the transcripts that were differentially expressed between the sexes by ANOVA with Bonferroni correction (Table 2).
