Variation Graphs (IMAGE) Bielefeld University Caption Special graphs represent connections between genomes as nodes. If individual genes of a single organism deviate significantly from the typical genes of its species, they are represented as conspicuous curves and lines. This is the case, for example, with genes that trigger hereditary diseases. Picture: Bielefeld University/R. Wittler Credit Bielefeld University/R.
