Pangaia Project (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. Credit Bielefeld University/R. Wittler Usage Restrictions The image may only be used with appropriate caption or credit.
