G-banding of plant chromosomes [PDF]

open access: yes, 1986
A method for the staining of the chromosomal material of plant cells so as to induce G-Bands, useful in plant genetic studies such as hydridization. G-Banding is induced by contacting living plant cells, such as those of plants of the family Gramineae ...

Cytogenetic description of Bunocephalus doriae Boulenger, 1902 (Siluriformes: Aspredinidae) from the Paraná River (Misiones, Argentina)

open access: yesNeotropical Ichthyology
In this work, Bunocephalus doriae was cytogenetically analyzed. A karyotype with a diploid number of 2n= 50 comprising 6m, 10sm, 6st, and 28a (FN= 72) chromosomes was observed.

The origin of human chromosome 2 analyzed by comparative chromosome mapping with a DNA microlibrary [PDF]

open access: yes, 1994
Fluorescencein situ hybridization (FISH) of microlibraries established from distinct chromosome subregions can test the evolutionary conservation of chromosome bands as well as chromosomal rearrangements that occurred during primate evolution and will ...

Comparative analysis of karyotypes of Chironomus solitus Linevich & Erbaeva, 1971 and Chironomus anthracinus Zetterstedt, 1860 (Diptera, Chironomidae) from East Siberia

open access: yesComparative Cytogenetics, 2015
A comparative chromosome banding analysis of Chironomus solitus Linevich & Erbaeva, 1971 and Chironomus anthracinus Zetterstedt, 1860 from East Siberia (Lakes Baikal, Gusinoe, Arakhley and Irkutsk Reservoir) showed close similarity of banding ...

The early evolutionary history of neo-sex chromosomes in Neotropical grasshoppers, Boliviacris noroestensis (Orthoptera: Acrididae: Melanoplinae) [PDF]

open access: yes, 2014
Neo-sex chromosomes are an important component of chromosome variation in Orthoptera, particularly South American Melanoplinae species, which have proven to be outstanding experimental model system to study the mechanism of sex chromosome evolution in ...

Banded karyotype of Nelore cattle (Bos taurus indicus Linnaeus, 1758) [PDF]

open access: yesComparative Cytogenetics, 2019
Chromosome banding techniques were applied and standardized to obtain karyotype characteristics for the first time in Brazil of Nelore cattle – Bos taurus indicus Linnaeus, 1758 – (bovine subspecies most prominent in Brazilian livestock).

Heterochromatin (C bands) in bovine chromosomes [PDF]

open access: yesHereditas, 2009
Metaphase chromosomes from cattle leukocytes were stained for constitutive heterochromatin. It was possible to demonstrate heterochromatin in the centromere regions of the autosomes but not of the X chromosome. The short arm and the centromere region of the Y chromosome were more faintly stained than the centromere regions of the autosomes.

Chromosome complement and meiosis in three species of the Neotropical bug genus Antiteuchus (Heteroptera, Pentatomidae, Discocephalinae) [PDF]

open access: yes, 2006
Orcein staining of spermatocytes was used to study the meiotic behavior of holocentric chromosomes in three member of the genus Antiteuchus (commonly known as stink bugs). We describe and illustrate the karyotype of Antiteuchus mixtus, A. sepulcralis and
