In a microchromosome-carrying laboratory stock of the normally all-female Amazon molly Poecilia formosa triploid individuals were obtained, all of which spontaneously developed into males. A comparison of morphology of the external and internal insemination apparatus and the gonads, sperm ploidy and behaviour, to laboratory-bred F(1) hybrids revealed that the triploid P. formosa males, though producing mostly aneuploid sperm, are partly functional males that differ mainly in sperm maturation and sexual motivation from gonochoristic P. formosa males.
在携带微小染色体的实验室品系中，正常情况下全部为雌性的亚马逊红腹丽鱼（Poecilia formosa）中获得了三倍体个体，这些个体均自发发育成雄性。将外部和内部授精器官和性腺、精子倍性和行为与实验室培育的 F1 杂种进行比较后发现，虽然三倍体 P. formosa 雄性产生的大多是非整倍体精子，但它们是部分功能正常的雄性，与雌雄同体的 P. formosa 雄性相比，主要在精子成熟和性动机方面存在差异。
