Allopolyploid
Definition
An organism, cell, or individual possessing more than two complete sets of chromosomes (being polyploid), resulting from the hybridization between two or more distinct species, followed by chromosome doubling. This hybrid structural phenomenon combines non-homologous genomes, being extremely widespread in the plant kingdom (for instance, in wheat or cotton), where it ensures enhanced vigor and restored fertility.
