Integrating cytogenetics and genomics in comparative evolutionary studies of cichlid fish
(Biomed Central Ltd., 2012-09-09)
Background: The availability of a large number of recently sequenced vertebrate genomes opens new avenues to integrate cytogenetics and genomics in comparative and evolutionary studies. Cytogenetic mapping can offer ...
A method for chromosome preparations from large fish specimens using in vitro short-term treatment with colchicine
(Birkhauser Verlag Ag, 1993-09-15)
This paper describes a new technique for preparing mitotic fish chromosomes using short-term in vitro treatment with colchicine. The results show that a large number of good quality metaphases (many suitable for chromosome ...

Analysis of spermiogenesis like a tool in the study of the triatomines of the Brasiliensis subcomplex
(2013-01-01)
The specific identification and systematic of triatomines have been based fundamentally on morphological observations. These organisms are classified into complexes and specific subcomplexes, principally for morphological ...

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 ...
Fish cytogenetic research: Advances, applications and perspectives
(1991-12-01)
Methods developed since 1976 for harvesting, preparing and banding fish chromosomes are now commonly used for taxonomic and phylogenetic studies, genetic control and chromosome manipulations in fish breeding and in monitoring ...
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, ...
First cytogenetic description of the species Rhamdella microcephala (Pisces, Hepapteridae)
(2003-03-01)
Cytogenetic studies were carried out on Rhamdella microcephala collected from the headwaters of the Machado river, a tributary of the Sapucaí river, Minas Gerais, Brazil. Sixteen specimens exhibited 2n=56 chromosomes, with ...
