Die Ursachen für Unterschiede zwischen den Arten ist ein großes Rätsel in der Biologie. Da Hybride aus Kreuzungen zweier Arten in der Regel steril sind, war eine genetische Kartierung in der Genetik sehr schwierig. Max Planck Forscher vom Friedrich Miescher Labor in Tübingen, haben jetzt die bahnbrechende Methode der „in vitro recombination“ zum Einsatz gebracht, bei der der Genaustausch direkt im Zellsystem erzielt wird. Dadurch konnten die Unterschiede zwischen Mausarten genetisch kartiert werden. Durch die Überwindung kreuzungsimmanenter Artgrenzen liefert diese Methode nun umfassende Einblicke in die Grundlagen genetischer Variation.
