Whole genome duplication (leading to polyploidy) is widely accepted as an important evolutionary force in plants, but it is less recognized as a driver of animal diversification. Nevertheless, it occurs across a wide range of animals; this review investigates why it is particularly common in fish and amphibians, while rare among other vertebrates. We review the current geographic, ecological and phylogenetic distributions of sexually reproducing polyploid taxa before focusing more specifically…

- Biology
- 2012
This study points to more frequent turnover of sex chromosomes than previously proposed, and suggests a lack of statistical support for male versus female heterogamy in the most recent common ancestors of frogs, salamanders, and amphibians in general.

Rise and Persistence of Animal Polyploidy: Evolutionary Constraints and Potential
- BiologyCytogenetic and Genome Research
- 2013
It is shown that in most animal asexual complexes clonal lineages may become established only under one ploidy level (usually either di- or triploidy), and that it is rather rare to see the coexistence of successful clones of different ploidies.
Polyploidy in Fish and the Teleost Genome Duplication
- Biology
- 2012
It is argued that, although evidence remains sparse, the TGD may have had a profound influence on the evolutionary success and the biodiversity of teleosts and the evolution of the authors' own paleopolyploid genome.
The gap in research on polyploidization between plants and vertebrates: model systems and strategic challenges
- Biology

The species of Carassius and the allopolyploid system of goldfish × common carp hybridization appear to be suitable models for unraveling the evolution and adaptation of polyploid vertebrates.
The Early Stages of Polyploidy: Rapid and Repeated Evolution in Tragopogon
- Biology
- 2012
It is proposed that substantial chromosomal instability results in karyotype restructuring, a likely common process following WGD and a driver of allopolyploid speciation, which has largely unexplored implications for gene losses, gains, and expression patterns.
Genetic and Genomic Interactions of Animals with Different Ploidy Levels
- BiologyCytogenetic and Genome Research
- 2013
This issue reviews a few polyploid animal species or biotypes where recently developed molecular and cytogenetic methods have significantly improved the understanding of their genetics, reproduction and evolution.
Polyploidy and interspecific hybridization: partners for adaptation, speciation and evolution in plants
- BiologyAnnals of botany
- 2017
Polyploidy results in immediate genetic redundancy and represents, with the emergence of new gene functions, an important source of novelty in plant evolution, and is illustrated by the huge angiosperm diversity that is assumed to originate from recurrent polyploidization events.
Whole genome duplication potentiates inter-specific hybridisation and niche shifts in Australian burrowing frogs Neobatrachus
- BiologybioRxiv
- 2019
It is proposed that Neobatrachus diploids may be suffering the early genomic impacts of climate-induced habitat loss, while tetraploids appear to be avoiding this fate, possibly due to widespread gene flow into tetra Ploidy lineages specifically.

The evidence for and against some of the traditional views on polyploidy is reviewed, with an attempt to synthesize factors promoting evolution through genome duplication in both groups.
Phylogenetic conservation of chromosome numbers in Actinopterygiian fishes

Overall, the phylogenetic analysis indicates a mosaic evolutionary pattern in which the forces that govern labile features of fish genomes must operate largely independently of those that operate to conserve chromosome numbers.

Speciation of clawed frogs occurred through bifurcation and reticulation of evolutionary lineages, and resulted in extant species with different ploidy levels. Duplicate gene evolution and expression…
Genome evolution and biodiversity in teleost fish
- Biology, Environmental ScienceHeredity

Comparison of data generated by current and future genome projects as well as complementary studies in other species will allow one to approach the molecular and evolutionary mechanisms underlying genome diversity in fish, and will certainly significantly contribute to the understanding of gene evolution and function in humans and other vertebrates.
Focus on polyploidy.
- BiologyThe New phytologist
- 2010
Over long periods of evolutionary time, polyploidy has increased morphological complexity and probably reduced the risk of species extinction (Fawcett et al., 2009), and thus has had a major impact on human societies and the development of an agrarian lifestyle.
Tetraploidy and the Evolution of Salmonid Fishes

It is proposed that genome doubling has taken place at least once in the evolution of vertebrates and isozyme studies that are consistent with this idea are described.
Polyploid incidence and evolution.
- BiologyAnnual review of genetics
- 2000
New estimates for the incidence of polyploidy in ferns and flowering plants are presented based on a simple model describing transitions between odd and even base chromosome numbers, and it is indicated that ploidy changes may represent from 2 to 4% of speciation events in flowering plants and 7% in f Ferns.
Advances in the study of polyploidy since Plant speciation

Despite the recent advances in the understanding of polyploid evolution, many exciting aspects remain under-investigated, and some of these include the consequences of genetic and genomic changes in naturalpolyploid populations, the physiological and ecological effects of polyPLoidy, and whether recurrent polyploidsy prompts evolution to repeat itself.
Did genome duplication drive the origin of teleosts? A comparative study of diversification in ray-finned fishes

The results suggest that the causes of diversification in large clades are likely to be complex and not easily ascribed to a single event, even a dramatic one such as a whole genome duplication.
