雌性的配偶复制已被证明发生在异种之间：雌性帆鳍海牛Poecilia latipinna复制了它们的雌核发育伙伴亚马逊海牛P.福尔摩沙的选择。雌性交配复制因此有助于维持这种无性-有性物种复合体，为与亚马逊雌性交配的雄性sailfin mollies提供优势;由于交配复制，这些雄性增加了对同种雌性的吸引力。在这里，我们表明，男性配偶复制，一个未报告的现象，也发生，它可以扭转男性的偏好同种女性。雄性交配复制也应该有助于雌核发育的维持，并可能有利于雄性快速评估雌性接受性，尽管有时会导致异种交配 *。
Female mate-copying has been shown to occur between heterospecifics: female sailfin mollies Poecilia latipinna copy the choice of their gynogenetic associates, Amazon mollies P. formosa. Female mate-copying thus contributes to the maintenance of this asexual-sexual species complex by providing an advantage to male sailfin mollies that mate with Amazon females; because of mate-copying these males increase their attractiveness to conspecific females. Here we show that male mate-copying, an unreported phenomenon, also occurs and that it can reverse male preferences for conspecific females. Male mate-copying should also contribute to the maintenance of gynogens and might be advantageous in allowing males a means to rapidly assess female receptivity although sometimes resulting in heterospedfic mating*.
