Allopolyploidy
Definition
The state, property, or structural phenomenon consisting of the presence of more than two chromosome sets originating from distinct species following interspecific hybridization. Allopolyploidy represents a major evolutionary engine in the plant kingdom, allowing the instantaneous emergence of new, fertile species reproductively isolated from their parents, combining the genetic advantages of both ancestral lines.
