Karyotypes and chromosomal characteristics of two species of bullhead catfish of the genus Liobagrus, namely L. marginatus and L. styani were examined by means of conventional (Giemsa and CMA(3) staining) and molecular (FISH with telomeric, 5S and 18S rDNA probes, respectively) cytogenetic techniques. The diploid numbers of L. marginatus and L. styani were 2n = 24 and 30 respectively. The karyotypes were: L. marginatus, 20m+2sm+2st in females and 19m+2sm+2st+1a in males; L. styani, 16m+ 10sm… CONTINUE READING
