Chromosomal painting and ZW sex chromosomes differentiation in Characidium (Characiformes, Crenuchidae)
(Biomed Central Ltd., 2014)
Homomorphic Sex Chromosomes and the Intriguing Y Chromosome of Ctenomys Rodent Species (Rodentia, Ctenomyidae)
(Karger, 2014-01-01)
Unlike the X chromosome, the mammalian Y chromosome undergoes evolutionary decay resulting in small size. This sex chromosomal heteromorphism, observed in most species of the fossorial rodent Ctenomys, contrasts with the ...
Similarity of heterochromatic regions in the stingless bees (Hymenoptera: Meliponini) revealed by chromosome painting
(Univ Florence Botany Inst, 2014-09-01)
Most Meliponini share a distinctive pattern of heterochromatin distribution in relation to other bees. In general, they present one euchromatic and one heterochromatic chromosome arm, a feature explained by minimum interaction ...
High similarity of U2 snDNA sequence between A and B chromosomes in the grasshopper Abracris flavolineata
(Springer, 2015)
B chromosomes are frequently enriched for a wide variety of repetitive DNAs. Among grasshoppers in the species Abracris flavolineata (Ommatolampidinae) the B chromosomes are submetacentric, C-negative and harbor repetitive ...
B chromosome dynamics in Prochilodus costatus (Teleostei, Characiformes) and comparisons with supernumerary chromosome system in other Prochilodus species
(Pensoft Publ, 2017-01-01)
Within the genus Prochilodus Agassiz, 1829, five species are known to carry B chromosomes, i.e. chromosomes beyond the usual diploid number that have been traditionally considered as accessory for the genome. Chromosome ...

High chromosomal instability in workers occupationally exposed to solvents and paint removers
(2016)
Background: Painters are exposed to an extensive variety of harmful substances like aromatic hydrocarbons used as solvents and paint removers, some of which have shown clastogenic activity. These substances constitute a ...
