Cytogenetic characterization of Lippia alba and Lantana camara (Verbenaceae) from Brazil
(Springer TokyoTokyoJapão, 2007)
Chromosome polymorphism of heterochromatin and nucleolar regions in two populations of the fish Astyanax bockmanni (Teleostei: Characiformes)
(2010-01-01)
Karyotype and other chromosomal markers as revealed by C-banding and silver (Ag) impregnation in two Astyanax bockmanni populations (Barra Seca Stream and Campo Novo River) were examined. The diploid chromosome number 2n ...
Cytogenetic markers as diagnoses in the identification of the hybrid between Piauçu (Leporinus macrocephalus) and Piapara (Leporinus elongatus)
(Sociedade Brasileira de Genética, 2008-01-01)
The genetic monitoring of interspecific hybrids involves the application of methodologies able to provide an easy and indubitable genetic characterization of both parental and hybrid individuals. In the present work, ...
Cytogenetical analyses in three Astyanax scabripinnis populations (Pisces, Characidae) from Minas Gerais State, Brazil
(2007-09-01)
Cytogenetical data in 3 populations of characid fish assigned to the complex of Astyanax scabripinnis from São Francisco river basin and Grande river basin, Minas Gerais State, Brazil, are presented for the first time. The ...
B chromosomes in species of the genus Prochilodus (Characiformes, Prochilodontidae): morphological identity and dispersion
(2014)
B chromosomes have attracted the attention of Neotropical fish cytogeneticists in recent years, both for their remarkable occurrence in this group and also because of the interest in studies of the genetic structure and ...
Banding and FISH in three species of Vernonia, subsection Macrocephalae (Asteraceae, Vernonieae)
(Springer WienWienAustria, 2012)
A ZZ/ZW sex chromosome system in Imparfinis mirini (Pisces, Siluriformes)
(1997-01-01)
The cytogenetic analysis of 21 specimens of Imparfinis mirini showed the presence of 2n = 58 chromosomes in animals of both sexes. The basic karyotype consists of 22 metacentric and 34 submetacentric chromosomes plus one ...
Cytogenetic analysis of five species of the subfamily Corydoradinae (Teleostei: Siluriformes: Callichthyidae)
(Sociedade Brasileira de Genética, 2004-01-01)
In the present study, five callichthyid species belonging to the subfamily Corydoradinae were karyotyped: three species of Aspidoras and two of Corydoras. The three species of Aspidoras had the same diploid number, 2n = ...
Cytogenetic markers as diagnoses in the identification of the hybrid between Piauçu (Leporinus macrocephalus) and Piapara (Leporinus elongatus)

Cytogenetic and molecular markers reveal the complexity of the genus Piabina Reinhardt, 1867 (Characiformes: Characidae)
(Sociedade Brasileira de Ictiologia, 2012-01-01)
Foram realizadas análises citogenéticas e moleculares em representantes do gênero Piabina. O estudo envolveu especificamente as espécies P. argentea e P. anhembi coletadas nas áreas das bacias hidrográficas dos rios ...
