Morphologically differentiated sex chromosomes in neotropical freshwater fish
(2001-12-01)
A general survey of the occurrence of morphologically differentiated sex chromosomes in the neotropical freshwater fishes is presented. The total number of 32 occurrences involving simple XX-XY and ZZ-ZW, and multiple ...
Cytogenetic characterization of the silverside fish Odontesthes regia (Humboldt, 1833) (Teleostei: Atheriniformes: Atherinopsidae) from Iquique, Chile
(2006-07-01)
This paper describes the karyotype of Odontesthes regia by means of Giemsa staining, C-banding, to reveal the distribution of the constitutive heterochromatin, and by Ag-staining and fluorescent in situ hybridization (FISH), ...

Comparison of cytogenetics with FISH in 40 myelodysplastic syndrome patients
(Elsevier B.V., 2002-11-01)
Karyotyping is important for diagnosis and prognosis of myelodysplastic syndrome (MDS). Using fluorescence in situ hybridization (FISH) either mitotic or interphase cells can be analyzed and a higher number of cells can ...
The karyotype of Scoloplax distolothrix (Teleostei: Siluriformes: Scoloplacidae)
(2006-09-01)
The karyotype of a fish species belonging to the family Scoloplacidae, Scoloplax distolothrix, is described for the first time. Cytogenetic studies showed that this species has 2n=50 chromosomes, 18 metacentrics, 18 ...

Molecular and cytogenetic analyses of cryptic species within the Synbranchus marmoratus Bloch, 1795 (Synbranchiformes: Synbranchidae) grouping: Species delimitations, Karyotypic evolution and intraspecific diversification
(2014-01-01)
The fish species Synbranchus marmoratus has been reported to exist as a species complex due to high intraspecific karyotypic variability in spite of the difficulty or impossibility to distinguish them using morphological ...
Occurence of karyotypical mosaicism in Trichomycterus paolence (Teleostei, Trichomycteridae)
(2002-10-01)
A chromosomal mosaic has at least two cell lineages with different karyotypes derived from a single zygote and the karyotype alteration can be numeric or structural as well. In the present paper were detected a numeric ...
