Heterotypic hybridizations. (a) A plot of a Cy3-labeled RNA from Antp^76B/TM3 adults competitively hybridized to the array with Cy5-labeled RNA prepared from wild-type adults. (b) The coefficients of variance (CV) for all gene elements in (a) are plotted out as a function of Cy3 signal intensity. (c) The CV plotted as a function of differential expression.
