Hybridization brings together chromosome sets from two or more distinct progenitor species.
Genome duplication associated with hybridization, or allopolyploidy, allows these …

Polyploidy (whole-genome duplication; WGD) is common in plants and has long been
considered as both an important speciation mechanism and a crucial component of plant …

Background Interspecific postzygotic reproduction isolation results from large genetic
divergence between the subgenomes of established hybrids. Polyploidization immediately …

Organisms such as allopolyploids and F1 hybrids contain multiple distinct subgenomes,
each potentially with its own evolutionary history. These organisms present a challenge for …

Whole-genome duplications are radical evolutionary events that have driven speciation and
adaptation in many taxa. Higher-order polyploids have complex histories often including …

Recent studies have shown that one of the parental subgenomes in ancient polyploids is
generally more dominant, having retained more genes and being more highly expressed, a …

Polyploidy is increasingly recognized as a driver of biological diversity. How and why
polyploidization affects gene expression is critical to understanding the link between ploidy …

Species are usually defined by reproductive isolation and are characterized by their gene
repertoire. These two aspects are consequences of events fixed during evolution, including …

Our understanding of polyploid genome evolution is constrained because we cannot know
the exact founders of a particular polyploid. To differentiate between founder effects and post …

The challenge of allelic diversity for assembling haplotypes is exemplified in polyploid
genomes containing homoeologous chromosomes of identical ancestry, and significant …
