polyploid wikipedia - EAS
- From Wikipedia, the free encyclopedia A polyploid complex, also called a diploid-polyploid complex, is a group of interrelated and interbreeding species that also have differing levels of ploidy that can allow interbreeding.

Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes, where each set contains one or more chromosomes and comes from each

Polyploidie, die auf der Vervielfachung von Chromosomensätzen innerhalb derselben Art beruht, wird als Autopolyploidie (bzw. Autodiploidie, Autotriploidie, Autotetraploidie etc.) bezeichnet, in Abgrenzung zur Allopolyploidie. Autopolyploide Pflanzen verfügen durch die Zunahme des Kernvolumens meist über größere Zellen. Vielfach sind die Blüten größer, was in der Pflanzenzüchtung ausgenutzt wird. Kommt Polyploidie nur in einzelnen somatischen Zellenvor, s…

- Polyploïdie is een gevolg van ploïdiemutaties, waarbij er of te veel chromosomen of te weinig chromosomen aanwezig zijn in de celkern. Deze mutaties ontstaan door een storing in de opbouw van microtubuli tijdens de mitose of de meiose. Dit heeft weer een gevolg voor de juiste verdeling van de chromosomen over de dochtercellen, maar het heeft geen gevolg voor de gene…

Polyploidi er en tilstand der celler og organismer har mer enn to sett kromosomer.De fleste eukaryoter er diploide; det vil si at de har to sett kromosomer, ett fra hver av foreldrene.Noen organismer, spesielt planter, er likevel polyploide.Polyploide celler finnes også i noen typer vev hos organismer som ellers er diploide, for eksempel menneskets leverceller.

Polypoid melanoma is a rare cutaneous condition, a virulent variant of nodular melanoma.: 696 Polypoid melanoma is a subtype of nodular melanoma, the most aggressive form of melanoma (a skin cancer). Polypoid melanoma, like all types of melanoma, starts in the cells that make melanin, which is the protective pigment that gives skin color.
- https://en.wikipedia.org/wiki/Ploidy
Ploidy (/ ˈ p l ɔɪ d i /) is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes.Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as.
