Abstract
The majority of prokaryotic species is oligoploid or polyploid. Polyploidy has many evolutionary advantages and has most probably evolved independently in different phylogenetic lineages. Various benefits are discussed, including resistance to double strand breaks and the usage of genomic DNA as a phosphate storage polymer. Intermolecular gene conversion leads to the equalization of genome copies. A high fraction of polyploid species in natural populations challenges the interpretation of sequence-based community structure analyses.
