A simple reliable PCR‐based sex test for the platyfish Xiphophorus maculatus is described using sex chromosome‐linked molecular markers. The test can distinguish sexes prior to dimorphic differentiation without killing the fish. The method also has potential in identification of male and female embryos prior to birth.
