Karyotypic evolution in multiple myeloma
Cancer Genetics and Cytogenetics, 1985A patient with IgG kappa multiple myeloma was studied cytogenetically prior to therapy and was found to have a clone of 55,XX cells. After treatment leading to a clinical response, the patient relapsed with a clone of 57,XX cells, which were derivatives of the original neoplastic cell line.

Subchromosomal karyotype evolution in Equidae
Chromosome Research, 2013Equidae is a small family which comprises horses, African and Asiatic asses, and zebras. Despite equids having diverged quite recently, their karyotypes underwent rapid evolution which resulted in extensive differences among chromosome complements in respective species.

Karyotype evolution in conifers
Feddes Repertorium, 2021AbstractThe present study describes the published karyotypes of 338 conifer taxa comprising of 302 species belonging to 59 genera of conifers. The somatic chromosome numbers range from 2n=18 inPhyllocladus(Podocarpaceae) to 2n=66 inSequoia sempervirens(Cupressaceae).

Karyotype Evolution: Concepts and Applications
, 2017The karyotype is the characterization of number, size, and morphology of the set of chromosomes of a species, as seen under the microscope. Studying the karyotypic evolution of a group of organisms is necessary to obtain data such as number of chromosomes, the position of the centromeres, and the number and positions of secondary constrictions and ...

American Journal of Primatology, 1983
AbstractGreat karyotypic diversity exists within the platyrrhine genus Aotus. Primarily by comparing banded karyograms of different forms of Aotus, the pattern of karyotypic evolution can be assessed. Out‐group comparisons are used to establish primitive and derived states of particular chromosomes, and a parsimonious cladogram is constructed.

Non-Sciuromorph Rodent Karyotypes in Evolution
Cytogenetic and Genome Research, 2012Rodents are, taxonomically, the most species-rich mammalian order. They display a series of special genomic features including the highest karyotypic diversity, frequent occurrence of complex intraspecies chromosome variability, and a variety of unusual chromosomal sex determination mechanisms not encountered in other mammalian taxa.

Karyotype evolution in chronic myelogenous leukaemia
Irish Journal of Medical Science, 1978The aetiological, diagnostic and prognostic significance of chromosomal findings in the bone marrow in CML are discussed. A classical case progressing to terminal blast crisis is presented and the associated karyotype evolution is described.

Karyotypic evolution in human malignant melanoma
Cancer Genetics and Cytogenetics, 1986Chromosome studies were performed on direct preparations, early passage cultures, and cell lines derived from melanocytic lesions of 37 patients. There were six congenital or common acquired nevi, six dysplastic nevi, one early primary melanoma (radial growth phase), three complex melanomas (RGP with foci of vertical growth phase), six advanced primary

Evolution of karyotypes in snakes
Chromosoma, 1972Karyotype analysis and morphometric measurement of the chromosomes of 17 species of snakes have been done. Chromosomes of different species so far worked out in each family have been compared using quantitative methods to derive chromosomal affinities between species of different taxonomic categories.

Systematic Zoology, 1983
Haiduk and Baker (1982) gave an insightful interpretation of rate variation in karyotype evolution. Their descriptive nomenclature, however, is misleading-"karyotypic megaevolution" (Baker and Bickham, 1980) is an inappropriate term to apply to what Haiduk and Baker recognize as simply an exceedingly rapid rate of karyotype evolution.
