Allelic expression analysis. a Comparison between allelic gene expressions. The FPKM values for allelic pairs of D. coronatus genes, 7306 (green cross) with a single C. elegans ortholog and 2526 (red cross) without C. elegans ortholog, are plotted in such a way that the lower value is on the X-axis and the higher value on the Y-axis. b Region with 10-fold difference in the allelic expression level. A 40kbp region in the scaffold scf7180000986740 (lower box) and its homologous region in the scaffold scf7180000986741 (upper box) are shown with the gene models and the histograms of RNA-seq coverage (pink or yellow). The allelic pair genes g14665.t1 and g14586.t1 show a big difference in the RNA-seq pattern (arrowheads), while others show almost identical patterns. The gene g14587.t1 seems to be inserted just upstream of gene g14586.t1 (dashed box)
