Impact of copy number on gene expression in NGP and IMR-32 cells. Frequency of genes (Y-axis) whose expression was high (black bars) or low (gray bars) according to copy number ratios (X-axis). High-level expression was defined as the top 7th percentile of all expression ratios, while low-level expression was defined as the bottom 7th percentile. The number of genes in the different copy number classes is indicated in parenthesis.
