Polyploidy is a condition in which the cells of an organism have more than one pair of (homologous) chromosomes. Most species whose cells have nuclei (eukaryotes)...

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

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

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

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

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

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

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

lamarckiana, was central to early genetics research into mutationism and polyploidy. It is also more occasionally done in the livestock and pet trades; some...

lima bean. In wheat, domestication involved repeated hybridization and polyploidy. These steps are large and essentially instantaneous changes to the genome...
