In addition to the viviparous fish Mollienesia formosa, two other species of poeciliids have recently been found to produce only female offspring. The young of these females, however, unlike those of M. formosa, inherit characteristics from any one of the several species of males used in experimental matings.
除了胎生鱼类 Mollienesia formosa 之外,最近还发现另外两个鳉鱼科物种只产生雌性后代。然而,这些雌性的后代与 Mollienesia formosa 的后代不同,它们继承了实验交配中使用的几种雄性鱼类中的任何一种的特征。
