Nearly four decades ago, Roose & Gottlieb (Roose & Gottlieb 1976 Evolution 30, 818–
830.(doi: 10.2307/2407821)) showed that the recently derived allotetraploids Tragopogon …

Perhaps all flowering plants have experienced one or more episodes of polyploidization at
some time in their evolutionary history. Recent evidence indicates that this genome doubling …

▪ 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 …

Polyploidy has played a major role in the evolution of many eukaryotes. Recent studies have
dramatically reshaped views of polyploid evolution, demonstrating that most polyploid …

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 …

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, or the duplication of entire genomes, has been observed in prokaryotic and
eukaryotic organisms, and in somatic and germ cells. The consequences of polyploidization …

Polyploidy, the condition of possessing more than two complete genomes in a cell, has
intrigued biologists for almost a century. Polyploidy is found in many plants and some animal …

Polyploid animals have independently evolved from diploids in diverse taxa across the tree
of life. We review a few polyploid animal species or biotypes where recently developed …

Polyploidy is a mutation with profound phenotypic consequences and thus hypothesized to
have transformative effects in plant ecology. This is most often considered in the context of …
