These criteria include the age of the patient, extent of disease spread, microscopic appearance, and genetic features including DNA ploidy and N-myc oncogene amplification ( N-myc regulates microRNAs ), into low, intermediate, and high risk disease.

It was originally developed as a model of cell nuclei in a tissue section in conjunction with the Reference Curve Method for correcting ploidy measurements by image analysis in a tissue section, but it is useful for evaluating any algorithm that corrects ploidy measurements for the effect of sectioning.

"Cultivar-groups " are taxonomic categories used by the International Code of Nomenclature of Cultivated Plants ( ICNCP ) to associate of cultivars ( cultivated varieties ) of plants with traits useful to morphological traits such as frost tolerance, tuber dormancy, daylength adaptation, and ploidy level.

"' Ploidy "'is the number of sets of chromosomes in a egg, which fuse into a single cell during the fertilization phase of sexual reproduction ) carries a full set of chromosomes that includes a single copy of each chromosome, as aneuploidy generally leads to severe genetic disease in the offspring.

Duesberg along with other researchers, in a 1998 paper published in " Proceedings of the National Academy of Sciences ", reported a mathematical correlation between chromosome number and the genetic instability of cancer cells, which they dubbed " the ploidy factor, " confirming earlier research by other groups that demonstrated an association between degree of aneuploidy and metastasis.

Because ploidy slows the tumour growth rate, Ujvari et al . posit that the DFTD removal programme selected for slower-growing tumours, and that disease eradication programmes may result in the evolution of DFTD . The strains may also complicate attempts to develop a vaccine, and the mutation of the cancer may mean that it could spread to other related species, like the quoll.

"Allium dregeanum " occurs at elevations of 100-1000m, and flowers in spring and early summer ( October to December ) . " Allium dregeanum " is also notable for its high chromosome counts : polyploidy is not uncommon in " Allium, " with 14 % of representative " Allium " species exhibiting more than two sets of chromosomes, but " Allium dregeanum " has particularly high ploidy levels, and can be octoploid or decaploid.

The tree appears to have been introduced to the USA, featuring in the 1904 catalogue of Frederick W . Kelsey as " Ulmus Wheatlyi " and also the catalogue of the Plumfield Nursery of Fremont, Nebraska, in 1934, its origin claimed as Holland, the description given as'a round-headed tree with small glossy leaves . . . . hybridized with American White Elm'( : " U . americana " ), which would seem unlikely given the ploidy differences.
