Molecular cytogenetics of Salminus fish (Characiformes) based on 5S and 18S rRNA genes hybridization, fluorochrome staining and C-banding.

Karyotype, mapping of nucleolar and 5S rRNA genes and distribution of constitutive heterochromatin supposedly AT-rich were characterized on two isolate populations of Salminus brasiliensis, the biggest characid fish, and three population of Salminus hilarii. The diploid number 2n=50 and the karyotype formulae (10M+20SM+20ST/A) were the same to Salminus… CONTINUE READING
