Occurrence of natural triploidy in Rhamdia quelen (Siluriformes, Heptapteridae)
Genetics and Molecular Research, 2010 Five specimens of Rhamdia quelen collected from the Lindóia Stream, PR, Brazil, were cytogenetically analyzed. The diploid chromosome number found was 58, including 30 metacentric, 16 submetacentric, 10 subtelocentric, and 2 acrocentric chromosomes. Supernumerary or B chromosomes, frequently observed in this fish group, were not detected.
