A YY male of the goldfish, Carassius auratus, was detected among offspring of an estrone-induced XY female mated with a normal XY male. There is convincing evidence of the reality of inversion of sex differentiation in the XY zygote by estrone as well as male heterogamety (hence, female homogamety) in the goldfish.
在由雌酮诱导的XY雌性与正常XY雄性交配产生的后代中，检测到一条YY雄性金鱼（Carassius auratus）。有确凿证据表明，雌酮可使XY受精卵的性别分化发生反转，同时也证明了金鱼存在雄性异配性别（因此，雌性同配性别）。
