Whole chromosome painting of B chromosomes of the red-eye tetra Moenkhausia sanctaefilomenae (Teleostei, Characidae)
(2015-01-01)
B chromosomes are dispensable genomic elements found in different groups of animals and plants. In the present study, a whole chromosome probe was generated from a specific heterochromatic B chromosome occurring in cells ...
Chromosomal divergence and evolutionary inferences in Rhodniini based on the chromosomal location of ribosomal genes
(Fundação Oswaldo Cruz, 2015)
Chromosomal characteristics and karyotype evolution of oxyopidae spiders (araneae, entelegynae)
(2011-05-16)
We made a cytogenetic analysis of four species of Oxyopidae and compared it with the karyotype data of all species of this family. In Hamataliwa sp, the mitotic cells showed 2n♂ = 26+X 1X 2 and telocentric chromosomes. The ...

Different responses to doxorubicin-induced chromosome aberrations in Brazilian deer species
(Funpec-editora, 2010-01-01)
The tendency toward chromosome fragility is one of the theories that may explain chromosome variation in brocket deer species (genus Mazama). We tested doxorubicin as an inducer of chromosome aberrations in lymphocytes of ...

Cytogenetic mapping of the W chromosome in the genus Leporinus (Teleostei, Anostomidae) using a highly repetitive DNA sequence
(Wiley-Blackwell, 2012-03-01)
The distribution of the Leporinus elongatus LeSpeI repetitive sequence in other Leporinus species was studied in an attempt to elucidate the evolutionary history of sex chromosomes in this genus using chromosome fluorescence ...

Genomic content and new insights on the origin of the B chromosome of the cichlid fish Astatotilapia latifasciata
(Springer, 2011-10-01)
B chromosomes are additional chromosomes widely studied in a diversity of eukaryotic groups, including fungi, plants and animals, but their origin, evolution and possible functions are not clearly understood. To further ...
