Polyploids—organisms that have multiple sets of chromosomes—are common in certain
plant and animal taxa, and can be surprisingly stable. The evidence that has emerged from …

Polyploids can be defined as organisms with one or more additional chromosome sets with
respect to the number most frequently found in nature for a given species. Triploids …

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 …

We review knowledge about the roles of sex chromosomes in vertebrate hybridization and
speciation, exploring a gradient of divergences with increasing reproductive isolation …

The radiation of Palearctic green toads (Bufotes) holds great potential to evaluate the role of
hybridization in phylogeography at multiple stages along the speciation continuum. With …

A unisexual species is generally associated with polyploidy, and reproduced by a unisexual
reproduction mode, such as gynogenesis, hybridogenesis or parthenogenesis. Compared …

Although polyploidy has been involved in speciation in both animals and plants, the general
perception is often that it is too rare to have been a significant factor in animal evolution and …

The cellular and molecular mechanisms governing sexual reproduction are conserved
across eukaryotes. Nevertheless, hybridization can disrupt these mechanisms, leading to …

Approximately 99.9% of vertebrate species reproduce sexually. The exceptional 0.1%
reproduce via asexual or clonal means, which vary wildly and are fascinating in their own …

Flow cytometry, a method of rapidly characterizing optical properties of cells and cell
components within individuals, populations, and communities, is advancing research in …
