Polyploid formation is connected with rapid genomic changes and /or with epigenetic changes in gene expression patterns.While polyploidy-induced deletions,inversions and transpositions are usually irreversible and represent true genetic changes,epigenetic modifications are potentially reversible and can create epialleles that are indistinguishable at the level of DNA sequence but different with respect to gene expression and chromatin features.Epialleles can contribute significantly to epigenetic diversity and therefore likely to the adaptation potential.
