Abstract Gymnotus inaequilabiatus has been the subject of few studies concerning organization its macro- and micro-karyotypic structures. This article aims to enhance existing cytogenetic data for G. from upper Paraná River basin by documenting karyotype other chromosomal characteristics, including ribosomal DNA (rDNA) retroelements Rex-1 Rex-3, which have yet be described this genus. The modal diploid number 2n = 54, distributed in 34m + 18sm +2a both sexes, was observed. Single nucleolar...
In fish species, heterochromatinization is one process that could trigger sex chromosome differentiation. The present article describes a nascent XX/XY system evidenced by heterochromatin accumulation and microsatellite (GATA)
