Two-dimensional hierarchical clustering heat map of the microarray data showing transcript expression profiles for genes (n = 233) expressed in ovary biopsies of female striped bass that produced low and high quality spawns.

<p>Levels of gene expression are indicated on the color scale to the right with numbers indicating the fold difference from the grand mean for all fish (shown in black and indicated by the zero value), red indicating increased transcript expression, and green indicating decreased transcript expression. Fish producing high or low quality spawns are grouped as indicated at the bottom of the figure. The clustering of individual genes with respect to their similarity in changes of expression between individual fish is represented by the dendrogram to the left. The dendrogram at the top shows similarities in gene expression patterns between individual fish regardless of group.
