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...

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

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...

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

simple derivation above can be generalized for more than two alleles and polyploidy. Consider an extra allele frequency, r. The two-allele case is the binomial...

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...
