The genetic condition of having three complete sets of chromosomes all from the same ancestral species.
From auto- (self) + triploidy (noun form of triploid). Genetics terminology describing the state or condition of autotriploidy.
Plant breeders actually exploit autotriploidy to create seedless fruits—if you can triple the chromosomes without crossing with another species, you get sterile plants that put energy into fruit rather than seeds.
