Chromosome polymorphism in Astyanax fasciatus (Teleostei, Characidae). 2 – Chromosomal location of a satellite DNA
(Cytogenetic and Genome Research, 2018)
Cytogenetic studies of three species of Glandulocaudinae (Pisces, Characiformes, Characidae)
(1995-01-01)
Cytogenetic studies of three species of the subfamily Glandulocaudinae showed that Mimagoniates microlepis presents 2n = 52 chromosomes (6M + 20SM + 18ST + 8A), Mimagoniates lateralis presents 2n = 52 chromosomes (6M + ...
Comparative analysis of sex chromosomes in Leporinus species (Teleostei, Characiformes) using chromosome painting
(2013-07-03)
Background: The Leporinus genus, belonging to the Anostomidae family, is an interesting model for studies of sex chromosome evolution in fish, particularly because of the presence of heteromorphic sex chromosomes only in ...
Cytogenetics of three breeds of river buffalo (Bubalus bubalis L.), with evidence of a fragile site on the X chromosome
(Elsevier B.V., 1998-02-01)
The cytogenetic study of 182 river buffalo (Bubalus bubalis L., 2n=50) of Murrah, Mediterranean and Jaffarabadi breeds, from the State of São Paulo, was carried out to characterize their chromosomes and to detect possible ...
First report of a B chromosome in a natural population of Astyanax altiparanae (Characiformes, Characidae)
(Sociedade Brasileira de Genética, 2008-01-01)
Several species of the genus Astyanax have already been genetically studied, and B-chromosomes have been considered to be an interesting feature in some species of this group. In the present paper we report, for the first ...
Reconstructing ancestral chromosome numbers and inflorescence features in Eleusininae (Poaceae: Chloridoideae: Cynodonteae)
(Oxford University Press, 2020)
Intrachromosomal distribution of telomeric repeats in Eumops glaucinus and eumops perotis (Molossidae, Chiroptera)
(2000-12-04)
The location of chromosomal telomeric repeats (TTAGGG)(n) was investigated in two species of the Molossidae family, Eumops glaucinus and Eumops perotis. The diploid chromosome number (2n) is 40 in E. glaucinus and 48 in ...
A new karyotype of oligoryzomys (sigmodontinae, rodentia) from central Brazil
(2003-09-01)
A new karyotype of the genus Oligoryzomys was described for specimens collected in Brazilian Cerrado in Tocantins and Goias States. Conventional staining, G-, C-banding, and Ag-NOR staining techniques were used for describe ...
Chromosome polymorphism and cytotype establishment in Bidens pilosa (Asteraceae)
(Faculty Press, 1999-01-01)
Chromosome evolution, in the Bidens genus, was by polyploidy mechanisms. The basic number to the genus is X = 12 chromosomes, as all the Fitchinae subtribe. The association of chromosome number and environment in these ...
Molecular characterization and chromosomal localization of two families of satellite DNA in Prochilodus lineatus (Pisces, Prochilodontidae), a species with B chromosomes
(2003-05-01)
Prochilodus lineatus, an abundant species in the Mogi-Guaçu river basin, represents a large part of the region's fishing potential. Karyotypic analyses based on classic cytogenetic techniques have revealed the presence of ...
