Polyploidy is a condition in which the cells of an organism have more than two paired sets of (homologous) chromosomes. Most species whose cells have nuclei...

all grasses are polyploid. Many animals are uniformly diploid, though polyploidy is common in invertebrates, reptiles, and amphibians. In some species...

meiosis which is sometimes called permanent odd polyploidy, although it can also occur with even polyploidy (e.g. in tetraploids or hexaploids). Regardless...

investigate the origin of a peculiar genetic component in Sequoioideae, the polyploidy of Sequoia—and generated a notable exception that calls into question...

ongoing discussion. Rapid sympatric speciation can take place through polyploidy, such as by doubling of chromosome number; the result is progeny which...

absence of mitosis, which leads to elevated nuclear gene content and polyploidy. Endoreduplication can be understood simply as a variant form of the mitotic...

include ectopic recombination, retrotransposition event, aneuploidy, polyploidy, and replication slippage. Duplications arise from an event termed unequal...

He also researched and wrote widely on the role of hybridization and polyploidy in speciation and plant evolution; his work in this area has had a lasting...

asexually much more easily than most animals. They are also capable of polyploidy – where more than two chromosome sets are inherited from the parents....

Species of Crepis: their interrelationships and distribution as affected by polyploidy and apomixis. In Crepis and some other perennial plant species, a polyploid...

gene transfer; new species can arise rapidly through hybridisation and polyploidy; and species may become extinct for a variety of reasons. Viruses are...

Sequencing of its genome showed that the evolution of avocados was shaped by polyploidy events and that commercial varieties have a hybrid origin. Avocado trees...
