From: Cross-species hybridisation of pig RNA to human nylon microarrays
Distribution of variable genes across expression categories. Genes were categorized according to their average median normalized log transformed intensity (undetectable 0; low, 0–1.3; medium, 1.3–3; or high, ≥ 3). Variable genes were identified as genes with a standard deviation greater than two times the average standard deviation of the human data. The total number of genes in each expression category, and the number of genes variable in pig, human, or both, are shown.
