Whole-genome duplication (polyploidization) is among the most dramatic mutational
processes in nature, so understanding how natural selection differs in polyploids relative to …

Background Modern allotetraploid cotton contains an “A” and “D” genome from an ancestral
polyploidy event that occurred approximately 1–2 million years ago. Diploid A-and D …

Of the many processes that generate gene duplications, polyploidy is unique in that entire
genomes are duplicated. This process has been important in the evolution of many …

Background Allopolyploid speciation requires rapid evolutionary reconciliation of two
diverged genomes and gene regulatory networks. Here we describe global patterns of gene …

Recent work has demonstrated that allopolyploid speciation in plants may be associated
with non-Mendelian genomic changes in the early generations following polyploid …

Premise A complicating factor in analyzing allopolyploid genomes is the possibility of
physical interactions between homoeologous chromosomes during meiosis, resulting in …

Genome duplication is thought to be central to the evolution of morphological complexity,
and some polyploids enjoy a variety of capabilities that transgress those of their diploid …

Polyploidization has occurred often in the evolutionary history of eukaryotes, yet we are only
now learning about the genetic and epigenetic events that occur in newly formed polyploids …

Polyploid formation and processes that create partial genomic duplication generate
redundant genomic information, whose fate is of particular interest to evolutionary biologists …

Background Polyploidy has played a prominent role in shaping the genomic architecture of
the angiosperms. Through allopolyploidization, several modern Gossypium (cotton) species …
