Abstract [en]

The formation of an allopolyploid species involves the merger of genomes with separate evolutionary histories and thereby different genomic legacies. Contrary to expectations from theory, genes from one are often lost preferentially in allopolyploids - there is biased fractionation. Here, we provide an overview of two ways in which the genomic legacies of the progenitors may impact the fate of duplicated genes in allopolyploids. Specifically, we discuss the role of homeolog expression biases in setting the stage for biased fractionation, and the evidence for transposable element silencing as a possible mechanism for homeolog expression biases. Finally, we highlight how differences between the progenitors with respect to accumulation of deleterious variation may affect trajectories of duplicate gene evolution in allopolyploids.
