Значение термина polyploid в knolik
polyploid - polyploid
polyploid - Having three or more times the haploid number of chromosomes. Polyploid individuals, sub-species and species are fairly common in plants (especially angiosperms) but rare in animals. This is mainly because polyploid organisms are sterile when crossed with diploids, and a polyploid suddenly arising in a diploid population can therefore only reproduce vegetatively, parthenogenetically, or by self-fertilization. These ways are commonly open to plants, but not commonly to animals. See also: Allote-traploid. Polyploid cells and tissues occur in otherwise diploid organisms (See also: Endomitosis).
