Molecular Characterization and Physical Mapping of Two Classes of 5S rDNA in the Genomes of Gymnotus sylvius and G. inaequilabiatus (Gymnotiformes, Gymnotidae)
(Karger, 2012-01-01)
The nucleotide sequences of the 5S rRNA multigene family and their distribution across the karyotypes in 2 species of Gymnotiformes, genus Gymnotus (G. sylvius and G. inaequilabiatus) were investigated by means of fluorescence ...
A radiation hybrid map of bovine X Chromosome (BTAX)
(2002-05-07)
We present a comprehensive radiation hybrid map of the bovine X chromosome (Chr) containing 20 new markers, including both microsatellites and expressed genes. This study was conducted with a 5000-rad whole genome RH cell ...
Chromosome Mapping of H1 Histone and 5S rRNA Gene Clusters in Three Species of Astyanax (Teleostei, Characiformes)
(Karger, 2011-01-01)
We report here on the physical mapping of the H1 histone genes (hisDNA) and the 5S ribosomal DNA (rDNA) in 3 Neotropical fish species of the genus Astyanax (A. altiparanae, A. bockmanni and A. fasciatus) and the comparative ...
Chromosome Evolution in African Cichlid Fish: Contributions from the Physical Mapping of Repeated DNAs
(Karger, 2010-01-01)
Cichlid fishes have been the subject of increasing scientific interest because of their rapid adaptive radiation that has led to extensive ecological diversity and because of their enormous importance to tropical and ...
Polytene chromosome map and inversion polymorphism in Drosophila mediopunctata
(Instituto Oswaldo Cruz, Ministério da Saúde, 2002)
Genetic differentiation among distinct karyomorphs of the wolf fish Hoplias malabaricus species complex (Characiformes, Erythrinidae) and report of unusual hybridization with natural triploidy
(Wiley-Blackwell, 2014-11-01)
In this study, genetic differentiation between karyomorphs A (2n=42) and D (2n=39/40) of the wolf fish Hoplias malabaricus, which is comprised of several cryptic species that present a wide variety of diploid chromosome ...
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 ...
Chromosomal Mapping of Repetitive DNA and Cytochrome C Oxidase I Sequence Analysis Reveal Differentiation among Sympatric Samples of Astyanax fasciatus (Characiformes, Characidae)
(Karger, 2013-01-01)
The genus Astyanax is a specious Neotropical fish group, occurring from the south area of the United States to Argentina. During the past few years, intensive studies on representatives of this group have been performed, ...
Water Buffalo Genome Science Comes of Age
(Ivyspring Int Publ, 2010-01-01)
The water buffalo is vital to the lives of small farmers and to the economy of many countries worldwide. Not only are they draught animals, but they are also a source of meat, horns, skin and particularly the rich and ...
