Cytogenetic analysis of Cycloramphus boraceiensis Heyer (Anura, Leptodactylidae)
(Sociedade Brasileira de Zoologia, 2001-03-01)
Cytogenetic studies on Cycloramphus boraceiensis Heyer, 1983 collected in Picinguaba, Ubatuba, State of São Paulo are presented. The species has 2n=26 karyotype formed by metacentrics, submetacentrics, and one telocentric ...
Cytogenetic characterization of distinct B chromosomes in a population of the fish Astyanax bockmanni (Teleostei, Characiformes)
(Univ Florence Botany Inst, 2012-01-01)
Individuals of Astyanax bockmanni from one population belonging to the Paranapanema River basin, southeastern Brazil, were cytogenetically examined. In the present paper, we report a diploid number of 50 chromosomes, with ...
Cytogenetic analysis of seven species of Eucalyptus L'Hér. (Myrtaceae)
(2000-07-01)
Seven species of the genus Eucalyptus were studied cytogenetically (E. deanei, E. dunni, E. grandis, E. maculata E. propinqua, E. saligna and E. tereticornis). The species showed a symmetrical karyotype with 2n=22 chromosomes, ...
High risk cytogenetic abnormalities in patients with multiple myeloma Características citogenéticas y detección de anormalidades de alto riesgo en mieloma múltiple
(Sociedad Medica de Santiago, 2019)
Background: Cytogenetic abnormalities observed in the bone marrow of patients with multiple myeloma (MM) are an important prognostic factor for risk stratification. Aim: To investigate karyotype characteristics and frequency ...
Cytogenetic Markers in Wild Population of Curimbata (Prochilodus lineatus) from Mogi-Guacu River
(Univ Tokyo Cytologia, 2009-09-01)
Within the genus Prochilodus, the species Prochilodus lineatus is certainly the most studied one from a cytogenetic point of view. In this study, a cytogenetic characterization of specimens of P. lineatus from Mogi-Guacu ...
Consolidation of the genetic and cytogenetic maps of turbot (Scophthalmus maximus) using FISH with BAC clones
(Springer, 2014-06-01)
Bacterial artificial chromosomes (BAC) have been widely used for fluorescence in situ hybridization (FISH) mapping of chromosome landmarks in different organisms, including a few in teleosts. In this study, we used BAC-FISH ...
Cytogenetic analysis of the genus thoropa cope, 1865 (Anura-cycloramphidae) with evolutionary inferences based on repetitive sequences
(2020-01-01)
Cytogenetics can be a useful tool to assist in taxonomic problems by adding information to the widely used morphological and molecular approaches. These taxonomic problems are especially common in anurans, once they are ...
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 ...
Cytogenetic studies of Mastacembelus armatus (Pisces, Mastacembelidae)
(Faculty Press, 1997-01-01)
The mitotic chromosomes, nucleolus organizer regions (NORs), C-banding pattern and nuclear DNA content of Mastacembelus armatus were studied. The karyotype (2n = 48; 10m + 6sm + 4st + 28a) was characterized by the presence ...
