  1. The number of orthologs linked to the U133A arrays is lower than the number of reference genes because of the same ortholog being shared by different reference genes. The number of reference gene ortholog pairs is always higher than the number of reference genes itself; this is attributed to the multiple orthologs for the common reference genes (see Figure 4).
