This property is systematized in the genus Brassica by the Triangle of U. The theory of this type of complex was first described by Babcock and Stebbins to explain genetic exchange between species incapable of directly breeding with each other. In humans, partial but not complete hydatiform moles exhibit this phenomenon, as do normal hepatocytes. It results from endoreplication in Drosophila salivary glands; in other cells it can also result from non- reduction during meiosis. Commonly occurring in plant endosperm and angiosperms, FTP identify this phenomenon in which cells possess more than two haploid sets of chromosomes.
