A whole genome duplication event is a genomic phenomena where an organism copies its entire genome, thereby creating a 2N ploidy where N was the ploidy prior to the duplication event. As many organisms that undergo these events are diploid, and hence go from 2N to 4N, whole genome duplication events are often referred to as tetraploidy events, although the nomenclature can be manipulated as per the number of haploid copies (i.e. hexaploidy for wheat).
One common way to detect whole genome duplications is through syntenic dotplots. CoGe's tools SynMap provides an easy to use interface for generating syntenic dotplots between any two genomes stored in the CoGe database.
