Venn diagrams of sex-biased genes.

For each of the three developmental stages (a) cercariae, (b) schistosomula s#2 and (c) adults, significant differences (Padj<0.05) between sexes were detected by DEseq analyses. Here are represented the number of sex-biased genes by stage and those that are shared between different stages: (A) when pooling male- and female-biased genes, or considering only (B) female-biased genes or (C) male-biased genes. (D) The table represents the number of sex-switching biased genes that are more expressed alternatively in females or in males depending on the developmental stage.
