Polyploidysearch for term

the presence of more than one chromosome set within the same nucleus. It originates from either whole-genome doubling (autopolyploidy) or by interspecific or intergeneric hybridizations followed by chromosome doubling (allopolyploidy). Polyploidy has been common throughout the evolution of plant genomes. Although most of the current genomes went through a diploidization process and only traces of ancient polyploidy events can be found today\, allopolyploidy is still observed inmany groups of plants\, including crops such as banana (Musa sp.)\, Brassica\, bread wheat (Triticum aestivum)\, durum wheat (Triticum durum)\, oat (Avena sativa)\, cotton (Gossypium sp.)\, canola (Brassica napus)\, coffee (Coffea sp.) and tobacco (Nicotiana tabacum).
