Figure 1.

Heat map representation of pair-wise gene expression in each sample. The dendrogram at the top of the figure indicates relatedness of the three samples based on overall gene expression values. The dendrogram on the left side of the figure orders genes into groups based on the divergence of expression values among the three samples. The colors display gene expression variance: red indicates a higher gene expression, green indicates lower expression and black indicates the median value. This figure was generated using a log scale of RPKM values.
