Sex-ratio distortion associated with the presence of a B chromosome in Astyanax scabripinnis (Teleostei, Characidae).

Cytogenetics and cell genetics - 1 Jan 1996

Vicente V E, Moreira-Filho O, Camacho J P

Abstract excerpt

Cytogenetic studies were conducted on 154 specimens of Astyanax scabripinnis collected at three localities in the Campos do Jordão region (State of São Paulo, Brazil). The C-banding pattern suggested that the metacentric B chromosome found in most of the specimens is an isochromosome derived from chromosome 24, the only chromosome in the standard complement that carries interstitial C-bands similar to those...
