Figure 3.

Dendrogram of gene expression patterns across samples for genes significantly different between tissues (ANOVA, p < 0.05). Clustering indicates similar expression patterns among samples (top axis) and among genes (left axis). Samples cluster as livers (yellow), hearts (pink) and brains (blue). Genes involved in oxidative phosphorylation are highlighted in green, and expression patterns that are consistent across all three populations are highlighted with a blue triangle.
