Hierarchical heat map of T. thynnus ESTs differentially expressed among male and female gonad tissue. A hierarchical clustered heat map showing the log₂ transformed expression values for microarray features on the BFT 4X44K Array following hybridization of mRNA preparations from T. thynnus male and female gonad tissue. The individual features are not labelled but are pictured horizontally showing their relative expression values across all replicates of the male and female gonad tissues. The intensity of the color scheme is calibrated to the log₂ expression values such that red refers to higher transcript abundance and blue refers to lower transcript abundance. The features displayed are those which are significantly different (p<0.05) between the male and female conditions and have a log₂ fold change value greater than one.
