The aim of this study was to characterize cytogenetically one population of the fish
Moenkhausia sanctaefilomenae (Steindachner, 1907), with emphasis on the analysis of B …

The cytogenetic characteristics of five fish species of the Moenkhausia are described, based
on the analysis of specimens collected in different headwater. All the species analyzed …

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 …

Individuals of Astyanax bockmanni from one population belonging to the Paranapanema
River basin, southeastern Brazil, were cytogenetically examined. In the present paper, we …

Background B chromosomes, also known as supernumerary or accessory chromosomes,
are additional chromosomes over the standard complement found in various groups of …

Some of the largest B chromosomes so far discovered in vertebrates are present in the
cyprinid fish Alburnus alburnus. Previous cytogenetic analyses revealed a diploid …

Six populations of the fish Prochilodus lineatus were analysed for B chromosome frequency.
A study of spermatogenesis revealed the absence of B accumulation during the stages …

The chromosomes of Barbus barbus L. and Barbus peloponnensius V. from the river Vapa,
Serbia (Yugoslavia) were cytogenetically studied. Barbus barbus has a diploid chromosome …

B chromosomes are additional elements to standard karyotypes observed in different
species of fishes, especially in Curimatidae. However, despite studies demonstrating the …

In freshwater Neotropical fishes, supernumerary chromosomes or B chromosomes have
been found in 61 species so far, distributed in 16 families of seven different orders and in …
