Gene expression variation across samples of nine tissue types in seven individuals of five caecilian species. a Heatmap showing correlation between variance-mean expression levels for protein-coding genes in different tissue samples (see Table S2 for sample details). b PCA plot of PC1 versus PC4 showing variance among gene expression levels in various tissue types across the five sampled caecilian species
