Background Most, if not all, green plant (Virdiplantae) species including angiosperms and
ferns are polyploids themselves or have ancient polyploid or whole genome duplication …

Polyploidy has been hypothesized to be both an evolutionary dead-end and a source for
evolutionary innovation and species diversification. Although polyploid organisms …

Publisher Summary This chapter provides an outline of the methods used for classifying and
identifying polyploid animals, followed by a discussion of proposed explanations for its …

Polyploidy, resulting from the duplication of the entire genome of an organism or cell, greatly
affects genes and genomes, cells and tissues, organisms, and even entire ecosystems …

▪ Abstract Changes in ploidy occurred early in the diversification of some animal and plant
lineages and represent an ongoing phenomenon in others. While the prevalence of …

Highlights•Polyploidy is a common evolutionary feature in all eukaryotes especially in
plants.•Ploidy and intergenomic hybridization induce genetic and epigenetic changes.•DNA …

Polyploids are traditionally classified into allopolyploids and autopolyploids, based on their
evolutionary origin and their disomic or multisomic mode of inheritance. Over the past …

Polyploidy in populations of well-differentiated plant species is now widely recognized (1, 2).
Most reports, however, are limited to a few individuals from one or several populations and …

Polyploidy played a significant role in the origin and evolution of many plant species. The
primary phylogenetic effect of polyploidy is to stabilize selected hybrid genotypes. It also …

Polyploidy, or whole genome multiplication, is ubiquitous among angiosperms. Many crop
species are relatively recent allopolyploids, resulting from interspecific hybridization and …
