Noun

dysploidy (uncountable)

  1. Variation in the chromosome number in a population by less than a whole set of chromosomes, typically because of chromosomal rearrangements.
    • Of course the inference that polyploidy underpins the dominance of even over odd chromosome numbers must be approached cautiously because of the confounding effects of dysploidy (a change in chromosome number resulting from the breakage and fusion of chromosomes without net gene loss or gain).1997, Karl J. Niklas, The Evolutionary Biology of Plants, page 29
    • FISH with rRNA genes can also help to detect recent polyploidization (duplication or dysploidy), since the number of 5S rDNA and 45S rDNA sites sometimes doubles with polyploidization (Souza et al. 2010).2015, Prabhu Shankar Lakshmanan et al., “Karyotype analysis and visualization of 45S rRNA genes using fluorescence in situ hybridization in aroids (Araceae)”, in Comparative Cytogenetics, volume 9...
