WebPaleopolyploidy is the result of genome duplications which occurred at least several million years ago (MYA). Such an event could either double the genome of a single species (autopolyploidy) or combine those of two species (allopolyploidy).Because of functional redundancy, genes are rapidly silenced or lost from the duplicated genomes.Most …
