Polyploid evolution: keeping the peace at genomic reunions.
Incompatible gene or chromosomal combinations brought together in allopolyploid genomes cannot be purged through Mendelian segregation. But recent studies suggest that the elimination of DNA sequences and alteration of DNA methylation patterns may permit the restoration of fertility in some allopolyploids.
