Genetic structure of brazilian populations of triatoma sordida (stal, 1859) (hemiptera, triatominae) by means of chromosomal markers
(2019-01-01)
Triatoma sordida is among the main Brazilian species considered as Chagas disease vectors. The genetic studies are directed mainly to phylogenetic questions because this species possibly have suffered cryptic speciation. ...
A comparative study of the recombination pattern in three species of Platyrrhini monkeys (primates)
(Springer, 2011-10)
Homologous chromosomes exchange genetic information through recombination during meiotic synapsis, a process that increases genetic diversity and is fundamental to sexual reproduction. Meiotic studies in mammalian species ...
Sex chromosome differentiation in Belostoma (Insecta: Heteroptera: Belostomatidae)
(Funpec-editora, 2012-01-01)
Belostoma, a genus of the family Belostomatidae, includes species of great ecological importance as biocontrol agents. Few species of these species have been the subject of cytogenetic analyses. Karyotypic evolution in ...
Comparative Cytogenetic Analysis of the Genus Symphysodon (Discus Fishes, Cichlidae): Chromosomal Characteristics of Retrotransposons and Minor Ribosomal DNA
(Karger, 2009-01-01)
As part of a genetic screening program for wild Discus fishes, we analyzed karyotypes and cytogenetic characteristics of Symphysodon aequifasciatus, S. discus and S. haraldi using C-banding and fluorescent in situ hybridization ...

Control of oocyte maturation
(2014-01-01)
Oocyte maturation is a complex process involving nuclear and cytoplasmic maturation. The nuclear maturation is a chromosomal segregation and the cytoplasmic maturation involves the reorganization of the cytoplasmic organelles, ...
