In der Natur kommt es vor, dass sich zwei unterschiedliche Pflanzenarten miteinander kreuzen. Das ist im Normalfall ein Problem, da die Erbinformation der beiden Eltern nicht zueinander passt. Doch manchmal hilft die Natur mit einem Trick nach. Statt, wie normalerweise üblich, nur jeweils die Hälfte der in Vater und Mutter enthaltenen Erbinformation an die Kinder weiterzugegeben, reichen beide Pflanzen die gesamte Information an die Nachkommen weiter, das heißt die Chromosomensätze werden addiert. So finden die Chromosomen während der Meiose einen passenden Partner, die Pflanzen bleiben fortpflanzungsfähig und eine neue Art ist entstanden.
