Figure 1

Relative normalized expression levels of imprinted genes in human and mouse. The figure summarizes the average (of normalized expression levels) of gene specific probes (annotated with the same gene name after normalization) of repeated array experiments. (a) A heatmap plot of biclustering (euclidean distance, average linkage) of human imprinted genes expression levels is shown. The third split within the genes tree is marked with a red cross. (b) A heatmap plot of biclustering (euclidean distance, average linkage) of mouse imprinted genes expression levels is shown. The third splits within the genes trees are marked by red crosses.
