Distribution of d/a values for 70-mer array differentially expressed genes. Distributions of d/a (type I) ratios for differentially expressed genes based on the 70-mer oligonucleotide microarray data. (A) The d/a distributions for all differentially expressed genes. The distributions of the four hybrids are very similar to one another and peak at approximately zero, as was observed in Affymetrix microarray data. (B) The d/a distributions for the subset of differentially expressed genes that are also represented with features on the Affymetrix platform. The distributions are similar to those in (A). In both (A) and (B), the proportion of DE genes with d/a values above 3.0 or below -3.0 are all plotted as a single data point. The proportion of d/a values above 3.0 and below -3.0 for hybrid B84 × B73 plotted beyond the range of the displays and are not shown.
