A database of amphibian karyotypes
Chromosome Research, 2019One of the first characteristics that we learn about the genome of many species is the number of chromosomes it is divided among. Despite this, many questions regarding the evolution of chromosome number remain unanswered. Testing hypotheses of chromosome number evolution using comparative approaches requires trait data to be readily accessible and ...

Heterochromatin, colchicine, and karyotype
Chromosoma, 1965Species of Chilocorus differ in chromosome number owing to centric fusion of metacentric chromosomes. The concomitant loss of arms is tolerated because in all unfused chromosomes one arm is completely heterochromatic, the other euchromatic. Under the influence of colchicine, the arms of unfused and fused chromosomes contract differentially.

An unusual karyotype in preleukemia
Cancer Genetics and Cytogenetics, 1982A case of a myeloproliferative disorder classified as preleukemia is described in which the patient developed a single, complicated, abnormal karyotype in 100% of the bone marrow cells (45, XY, -2, -5, -7, -8, -11, -12, -13, -14, + t(2;5), +t(11;12), +t(16;17), +17, plus three or four dicentric markers).

JAMA: The Journal of the American Medical Association, 1971
To the Editor.— The letter of Miller et al ( 214 :2337, 1970) describes a young woman with some of the features of Turner's syndrome. The karyotype reproduced in the article is likely to mislead readers who are not familiar with chromosome morphology. The third pair of chromosomes in group A is mislabeled as is the sex chromosome pair (XX). The latter

Annual Review of Ecology and Systematics, 1971
A comprehensive review of the karyotype in plant systematics was pub lished by Lewitsky (83) 40 years ago under this same title. He was dissatis fied with the narrow use of meager karyological data and included his own more complete work on several genera of the Ranunculaceae subfamily Hel leboreae.

The representation of the systematically arranged chromosomes of a cell is called the karyotype of the cell (Figs. 3 and 4). In a broader sense the term karyotype is also used in reference to a particular individual inferring that all the (somatic) cells have the same karyotype.
