The Y Chromosome of the Atelidae Family (Platyrrhini): Study by Chromosome Microdissection
(KARGER, 2009)
In order to study the intergeneric variability of the Y chromosome, we describe the hybridization of the Y chromosome of Brachyteles arachnoides, obtained by microdissection, to metaphases of Ateles belzebuth marginatus, ...
Chromosome homologies of the highly rearranged karyotypes of four Akodon species (Rodentia, Cricetidae) resolved by reciprocal chromosome painting: the evolution of the lowest diploid number in rodents
(SPRINGER, 2009)
Traditionally comparative cytogenetic studies are based mainly on banding patterns. Nevertheless, when dealing with species with highly rearranged genomes, as in Akodon species, or with other highly divergent species, ...
Variable patterns of Y chromosome homology in Akodontini rodents (Sigmodontinae): a phylogenetic signal revealed by chromosome painting
(SPRINGERDORDRECHT, 2012)
The Akodontini is the second most speciose tribe of sigmodontine rodents, one of the most diverse groups of neotropical mammals. Molecular phylogenetic analyses are discordant regarding the interrelationships of genera, ...
Chromosome painting of Z and W sex chromosomes in Characidium (Characiformes, Crenuchidae)
(2013-01-24)
Some species of the genus Characidium have heteromorphic ZZ/ZW sex chromosomes with a totally heterochromatic W chromosome. Methods for chromosome microdissection associated with chromosome painting have become important ...
Chromosome painting of Z and W sex chromosomes in Characidium (Characiformes, Crenuchidae)
(2013-01-24)
Some species of the genus Characidium have heteromorphic ZZ/ZW sex chromosomes with a totally heterochromatic W chromosome. Methods for chromosome microdissection associated with chromosome painting have become important ...
Common Descent of B Chromosomes in Two Species of the Fish Genus Prochilodus (Characiformes, Prochilodontidae)
(Karger, 2013-01-01)
To ascertain the origin of B chromosomes in 2 fish species of the genus Prochilodus, i.e. P. lineatus and P. nigricans, we microdissected them and generated B-specific DNA probes. These probes were used to perform chromosome ...
The early evolutionary history of neo-sex chromosomes in Neotropical grasshoppers, Boliviacris noroestensis (Orthoptera: Acrididae: Melanoplinae)
(Czech Academy of Science, 2014-07)
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 ...
Origin of B chromosomes in the genus Astyanax (Characiformes, Characidae) and the limits of chromosome painting
(Springer, 2016-06-01)
Eukaryote genomes are frequently burdened with the presence of supernumerary (B) chromosomes. Their origin is frequently investigated by chromosome painting, under the hypothesis that sharing the repetitive DNA sequences ...
Chromosomal Mapping of Repetitive DNAs in Characidium (Teleostei, Characiformes): Genomic Organization and Diversification of ZW Sex Chromosomes
(Karger, 2015-01-01)
The speciose neotropical genus Characidium has proven to be a good model for cytogenetic exploration. Representatives of this genus often have a conserved diploid chromosome number; some species exhibit a highly differentiated ...
B chromosome variants in Prochilodus lineatus (Characiformes, Prochilodontidae) analyzed by microdissection and chromosome painting techniques
(2016-04-02)
Several cytogenetic studies in Prochilodus lineatus (Valenciennes 1836) describe a striking system of supernumerary microchromosomes revealing the occurrence of three morphological types visualized as acrocentric, metacentric ...
