Abstract
Cytogenetic studies were made in 2 populations of Hoplias sp. (Pisces, Erythrinidae) from the Lobo Reservoir, State of Sao Paulo, Brazil, and from the Aripuana River, State of Mato Grosso, Brazil. The 2 populations show evidences of multiple sex chromosomes. The animals from the Lobo Reservoir have an X1X1X2X2/X1X2Y mechanism, and those from the Aripuana River an XX/XY1Y2 mechanism; this represents the first such case described for fishes.This publication has 2 references indexed in Scilit:
