Summary

Description
English: The idealized evolution of a gene (lines) is shown from a common ancestor in an ancestral population, descending to three populations labelled A, B and C. There are two speciation events, each occurring at the junctions shown as an upside down Y. There are also two gene-duplication events, depicted by a horizontal bar. Ref.: W. M. Fitch: Homology a personal view on some of the problems. In: Trends in genetics : TIG. Band 16, Nummer 5, Mai 2000, S. 227–231. PMID 10782117.
Deutsch: Die idealisierte Entwicklung eines Gens aus einer Urpopulation A in zwei neue Populationen B, C. Eine schräglinige Verzweigung stellt ein Artbildungsereignis, eine horizontale Linie eine Genverdopplung dar. Zwischen B und A findet außerdem horizontaler Gentransfer statt.
