Abstract
Combining the genomes of two species through hybridization and chromosome d oubling can create a new allopolyploid species virtually overnight. Althoug h common in Nature, such genetic mergers might not be easy. Recent studies, mostly in plants, suggest that polyploidization can induce a flurry of gen etic and epigenetic events that include DNA sequence elimination and gene s ilencing.
