Quantile quantile (QQ) plots of the differences of log rpm (log( p 1 ) - log( p 2 )) confirming the Gaussian distribution as a reasonable approximation of the biological variation. A.QQ plots of log(p1) - log(p2) for genes with average log rpm within 2 ± 0.05. B) For genes with average log rpm within 1.6 ± 0.05 C) For genes with average log rpm within 1.2 ± 0.05 D) For genes with average log rpm within 0.8 ± 0.05. The straight lines in all figures have a slope 0.28, suggesting that biological variation does not depend on average rpm.
