Accessory gland-specific genes were upregulated in the sensitive Y chromosome males. (a) Average fold change in the expression of the 37 accessory gland-specific genes that were differentially expressed across lines (P<0.01). Darker shades denote lower expression level; lighter shades denote higher expression level (Supplementary Figure S3). (b) Average relative expression level of these 37 genes (P<0.01, dark gray), as compared with that of the other 39 accessory gland-specific genes that were stably expressed across genotypes (0.05<P<0.95, light gray). Error bars denote >99% confidence intervals for the average fold differences. (c) Three serine protease inhibitors were upregulated in the sensitive Y chromosome males: serine protease inhibitor 7 (Spn7, black bars), serine protease inhibitor 2 (Spn2, dark gray) and serine protease inhibitor 3 (Spn3, light gray).
