Combining two or more related homoeologous genomes in a single nucleus, newly formed
allopolyploids must rapidly adapt meiosis to restore balanced chromosome segregation …

Polyploidy is a major force shaping eukaryote evolution but poses challenges for meiotic
chromosome segregation. As a result, first‐generation polyploids often suffer from more …

Allopolyploids arise from the hybridization of two species concomitant to genome doubling.
While established allopolyploids are common in nature and vigorous in growth, early …

Whole-genome duplication resulting from polyploidy is ubiquitous in the evolutionary history
of plant species. Yet, polyploids must overcome the meiotic challenge of pairing …

Allopolyploidy is a significant evolutionary process, resulting in new species with diploid or
greater chromosome complements derived from two or more progenitor species. We …

Allopolyploids contain complete sets of chromosomes from two or more different progenitor
species. Because allopolyploid hybridization can lead to speciation, allopolyploidy is an …

Most diploid organisms have polyploid ancestors. The evolutionary process of
polyploidization is poorly understood but has frequently been conjectured to involve some …

Polyploidy is a major driver of evolutionary change. Autopolyploids, which arise by within-
species whole-genome duplication, carry multiple nearly identical copies of each …

Polyploidization is an important mechanism for introducing diversity into a population and
promoting evolutionary change. It is believed that most, if not all, angiosperms have …

Highlights•Arabidopsis is an emerging model for polyploid meiosis.•Outcrossing auto and
allopolyploids have distinct genotype frequency distributions.•Meiosis in first generation …
