Interindividual size heteromorphism of NOR and chromosomal location of 5S rRNA genes in Iheringichthys labrosus
Twenty-five specimens of Iheringichthys labrosus from the Capivara Reservoir were analysed cytogenetically. AgNORs were detected in a pair of ST chromosomes, in the telomeric region of the long arm. Some individuals showed size heteromorphism of this region between homologous chromosomes. Treatment...
