Figure 2.

Regional clusters of highly expressed genes in the chicken genome. Gene expression is plotted for chicken chromosomes 1-15, 17-24, 26-28, and Z. The expression values are plotted as a moving window with a size of 39 genes to calculate the running median along the chromosomes. The log2 transformed intensities of green channel are shown; the start of the chromosomes correspond with the top of the plot, and the window width indicates the expression levels, ranging between 6.6-8.3 (log2 scale).
