Karyotypes of male (a, b) and female (c, d) Lignobrycon myersi after Giemsa staining (a, c) and C-banding (b, d), bearing ZZ (1st pair) and ZW sex chromosomes, respectively. On the right, the Ag-NOR bearing chromosomes (e, i), GC-rich region (CMA3+/DAPI-) (f, j), 18S rDNA (g, k) and 5S rDNA (h, l) in males (e–h) and females (i–l).
