Autopolyploidy

 

a multiple increase in the cells of an organism of the initial number of chromosomes characteristic of the given species. Autopolyploidy is significant in the ontogeny of plants and animals and also in phylogeny, primarily in plants. In animals, however, it is significant in parthenogenesis. By artificially inducing autopolyploidy using high temperatures, irradiation, and chemical compounds, it has been possible to create autopolyploidal forms and varieties of buckwheat, rye, sugar beet, and other crops.

Karyotype analysis supported autoallopolyploidy (Saylor and Simons, 1970) and allozyme inheritance patterns provided some evidence for chromosomal duplication that would be consistent with autopolyploidy in the evolution of the genome of redwood (Rogers, 1997).
Two extreme categories of polyploidy can be recognized: autopolyploidy and allopolyploidy.
