Subsets of gene-expression profiles from wild-type gonads. Scatterplots of hybridization intensities for XX;AA ovary (y-axis) versus X;AA testis (x-axis) samples to elements corresponding to (a) all genes, (b) genes encoding cytoplasmic or mitochondrial proteins, and (c) de facto housekeeping genes (showing high intensity and low variance across all experiments). Data points and regression lines (trendlines) correspond to elements reporting autosomal genes (black) and X-chromosome genes (red).
