Figure 2

Average relative expression for unbiased, female-biased, and male-biased gene sets for the three tissues analyzed. Sex-biased was determined for each tissue separately, and genes that were differentially expressed between males and females (p_adj < 0.05) with an absolute log₂ fold-change > 1 were classed as sex-biased. Pink bars represent the average across female replicates, blue bars represent the average across male replicates. 95% confidence whiskers are shown, based on bootstrapping (1000 repetitions). Due to small sample sizes, the female-biased Z-linked category is not shown. See Table 1 for numbers of genes in each expression class. The Y-axis corresponds to relative expression levels.
