A change of ploidy can modify epigenetic silencing.
O Mittelsten Scheid, L Jakovleva… - Proceedings of the …, 1996 - National Acad Sciences
A silent transgene in Arabidopsis thaliana was reactivated in an outcross but not upon
selfing of hemizygous plants. This result could only be explained by assuming a genetic …

Genetic and epigenetic interactions in allopolyploid plants
L Comai - Plant Gene Silencing, 2000 - Springer
Allopolyploid plants are hybrids that contain two copies of the genome from each parent.
