From: Orthologous gene-expression profiling in multi-species models: search for candidate genes
Overlaps between rat (U34A GeneChip), mouse (U74A GeneChip) and human (U95A GeneChip) Affymetrix array platforms based on the human (U133A GeneChip) ortholog assignments. The sum of numbers inside each circle represents the total number of ortholog pairs formed with reference genes on the U133A GeneChip by corresponding arrays (see also Table 1). The reference genes formed 3,077 pairs with corresponding orthologs that were represented on all depicted arrays.
