The importance of hybridization in plant speciation and evolution has been debated for
decades, with opposing views of hybridization as either a creative evolutionary force or …

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 …

The prevalence of autopolyploids in angiosperms has long been a subject of debate.
Müntzing (1936) and Darlington (1937) concluded that autopolyploids were common and …

▪ Abstract Polyploidy is widely acknowledged as a major mechanism of adaptation and
speciation in plants. The stages in polyploid evolution include frequent fertility bottlenecks …

Three published estimates of the frequency of polyploidy in angiosperms (30 to 35 percent,
47 percent, and 70 to 80 percent) were tested by estimating the genome size of extinct …

▪ Abstract Here we review the biology of early generation neopolyploids and discuss the
profound changes that accompany their formation. Newly formed auto-and allopolyploids …

Abstract About 12,000 years ago, humans began the transition from hunter-gathering to a
sedentary, agriculture-based society. From its origins in the Near East, farming expanded …

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 …

summary The production of 2n gametes in plants, ie gametes with a somatic chromosome
number, is considered to be the dominant process involved in the origin of polyploid plants …

Enormous strides have been made in the study of polyploidy over the last 20 yr. Here, we
highlight some of these discoveries and note where our understanding of polyploid …
