In the guppy Poecilia reticulata, females that mated with attractive males produced offspring with more male-biased sex ratios than those that mated with less attractive males. Since sexual attractiveness of male guppies is a heritable trait, such manipulation of offspring sex ratios depending on male attractiveness may be adaptive. In order to clarify whether female or male parents execute the offspring sex ratio manipulation, an examination in which the relative attractiveness of males was manipulated was conducted. Results of this study indicate that female parents have responsible for offspring sex ratio manipulation.

在孔雀鱼Poecilia reticulata中，与有吸引力的雄性交配的雌性产生的后代比那些与不那么有吸引力的雄性交配的后代具有更多的雄性偏见。由于雄性孔雀鱼的性吸引力是一种可遗传的特征，这种根据雄性吸引力对后代性别比例的操纵可能是适应性的。为了澄清雌性或雄性父母是否执行后代性别比例操纵，进行了一项检查，其中雄性的相对吸引力被操纵。研究结果表明，雌性父母对后代性别比例的操纵负有责任。
