Gene environment comparison between C. elegans and Drosophila family 2 GPCRs genomic regions. Short-range linkage analysis of the region surrounding family 2 GPCRs on the C. elegans chromosome III and X with the Drosophila chromosome regions containing family 2 GPCR receptor genes. Genes are represented by horizontal bars and gene identification and chromosome position is given at the side. Family 2 GPCRs members are highlighted in bold. The lines represent the correspondence between the genes in each species. The dashed lines represent the common genes that were identified in both protostome and deuterostome genomes. For simplicity, only genes that are in common are represented.
