Figure 3

Quantitative differences in gene expression between sexes. Male to female expression ratios (log₂FC, Fold-change: Male/Female) plotted against the average expression intensity (log₂CPM, Counts per million) in (A) brain, (C) tail, and (E) gonads. Genes with greater than median-fold bias (FDR < 0.1) are shown in red while the others are shown by black dots or smoothened. The blue lines mark a 4-fold difference in expression between the sexes. Genes with sex-limited expression are underlined in black (E). The number of male-biased and female-biased genes in each comparison is mentioned at the top-right and bottom-right respectively in each figure. Heatmaps showing the mean centered log₂FPKM (Fragments per kilo base per million) for the highest differentially expressed genes (FDR < 0.001) and a 1.5 fold-change in the brain (B), 1.7 fold-change in the tail (D), and 32 fold-change in the gonad (F). The top 30 genes that show sex-biased expression in each tissue are listed and ranked by fold-change in grey text boxes at the left (female-biased genes) and at the right (male-biased genes).
