Annotation of probesets to multiple genes. Fraction of probesets on Affymetrix arrays that are annotated to multiple genes with each colour representing the probesets annotated to one or more genes. On average about 6.1% of probesets only target multiples genes in human, 4.6% in mouse and 5.6% in rat.
