GC and nitrogen content of expressed genes. We observe significant differences in the GC content of genes biased towards adult or larval L. fabarum in: (a) the 10% most highly expressed genes and (b) genes that are significantly differentially expressed between adults and larvae. In contrast, there is no difference in the nitrogen content of the same set of genes (c, d). P-values are from a two-sided t-test
