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....

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...

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

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

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

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...

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

1920s, that wheat was divided into 3 ploidy levels. As with many grasses, polyploidy is common in wheat. There are two wild diploid (non-polyploid) wheats...

between Poa supina and Poa infirma. Major chromosomal rearrangements after polyploidy have contributed to variation in genome size in Poa annua. It has a slightly...

Taro (/ˈtɑːroʊ, ˈtær-/; Colocasia esculenta) is a root vegetable. It is the most widely cultivated species of several plants in the family Araceae that...

major source of complexity comes from the occurrence of hybridization, polyploidy, and apomixis (asexual seed production), making species difficult to characterize...

prescriptions. Colchicine is widely used in plant breeding to induce polyploidy, in which the number of chromosomes in plant cells are doubled. This frequently...

the genus is 13, and most species are diploid (2n=26). However, natural polyploidy exists, particularly in Jasminum sambac (triploid 3n=39), Jasminum flexile...

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...

unisexual species of Ambystoma share no nuclear DNA with Ambystoma barbouri. Polyploidy, a numerical change in the number of chromosomes, is common in parthenogenic...
