Polyploidy, the state of having more than two full sets of chromosomes, has been
hypothesized to provide several evolutionary advantages to flowering plants including …

Inbreeding depression, the reduced fitness of inbred relative to outbred individuals was
described more than two centuries ago, long before the development of population genetics …

The evolutionary transition to self-compatibility facilitates polyploid speciation. In
Arabidopsis relatives, the self-incompatibility system is characterized by epigenetic …

Polyploidy, resulting from whole‐genome duplication (WGD), is ubiquitous in nature and
reportedly associated with extreme environments and biological invasions. However, WGD …

Early studies of the textbook mixed‐ploidy system Biscutella laevigata highlighted diploids
restricted to never‐glaciated lowlands and tetraploids at high elevations across the …

In this study, we aimed to systematically assess the frequency at which potentially
deleterious phenotypes appear in natural populations of the outcrossing model plant …

Premise Numerous studies have found a positive association between dioecy and
polyploidy; however, this association presents a theoretical conflict: While polyploids are …

The theoretical population dynamics of autopolyploids–organisms with more than two
genome copies of a single ancestral species–and their diploid progenitors have been …

Polyploidie hraje klíčovou roli v rostlinné evoluci. Mimo jiné má také zásadní vliv na migrační
schopnosti a adaptibilitu rostlin. Tato práce se věnuje shrnutí známých vlastností polyploidie …

This work had several overarching objectives, including i) to determine the current trends in
inbreeding and genetic diversity in dairy and beef cattle populations using large historical …
