Figure 3

Genes selected by differential expression on chromosomes 2, 11 and 17 from congenic microarray experiments. Each chromosome is shown as a vertical black bar with the IBD regions shown as horizontal gray lines along the chromosome. The olive vertical line to the right of the chromosome represents the congenic donor region. The color bars to the left of the chromosome are the confidence intervals of the pQTL identified in the legend. A description of the phenotypes is in Additional file 2. The total number of genes in 2 Mbp bins is plotted in red bars to the right of the chromosomes. The number of genes in 2 Mbp bins along the chromosome is plotted with narrow horizontal bars to the right of each chromosome: brown, total number of genes; yellow, number of genes represented in the microarray; green, number of genes expressed in at least one tissue; blue, number of genes differentially expressed in at least one tissue. The scale labeled "Gene counts" represents the number of genes.
