In Eupsophus migueli, an anuran species endemic to southern Chile, all males examined have a heteromorphic pair of chromosomes, a small metacentric and a telocentric of the same size. In females, the corresponding pair, No. 14, is telocentric. This suggests that this species has an XX/XY system of sex chromosomes. The male is the heterogametic sex.
在智利南部特有的无尾目物种米氏夜蟾（Eupsophus migueli）中，所有被检查的雄性都有一对异形染色体，一条小的中着丝粒染色体和一条大小相同的端着丝粒染色体。在雌性中，相应的第14对染色体是端着丝粒染色体。这表明该物种具有XX/XY性染色体系统。雄性是异配性别。
