Scatterplots of hybridization intensities from transformed XX;AA and X;AA tissues. Data points correspond to elements reporting autosomal genes (black) and X-chromosome genes (red). (a) XX;AA females transformed into somatic males (dsxswe/Df(3R)dsxM+15) compared with germlineless X;AA male progeny of homozygous tud1mothers and (b) XX;AA ovaries from ovo1/otu17females compared with X;AA ovaries from hs-tra83/+ males transformed into females. The expected twofold difference in gene expression in the absence of X-chromosome dosage compensation is shown as a red line.
