Diversification of a ZZ/ZW sex chromosome system in Characidium fish (Crenuchidae, Characiformes)

  title={Diversification of a ZZ/ZW sex chromosome system in Characidium fish (Crenuchidae, Characiformes)},
  author={Marcelo Ricardo Vicari and Roberto Ferreira Artoni and Orlando Moreira-Filho and Luiz Ant{\^o}nio Carlos Bertollo},
Karyotype and other chromosomal markers of Characidium cf. gomesi were analyzed using conventional (Giemsa-staining, Ag-NOR and C-banding) and molecular (Fluorescent in situ hybridization (FISH) with 18S and 5S rDNA biotinylated probes) techniques. Both sexes had invariably diploid chromosome number 2n = 50 while karyotypes of males and females differed. That of male consisted of 32 metacentric + 18 submetacentric chromosomes and that of female consisted 31 metacentric + 18 submetacentric + 1… CONTINUE READING
