依赖精子（或假配子）的孤雌生殖形式发生在各种动物中。遗传是典型的克隆和母系遗传（女性血统），但精子是需要启动正常发育。与真正的孤雌生殖相反（即，精子独立生殖），假配子孤雌生殖谱系必须与“精子供体”共存-例如，来自同种有性谱系的雄性，同种雌雄同体，或来自密切相关的有性物种的雄性。这样的精子捐献者对下一代的遗传没有贡献。依赖精子的孤雌生殖的寄生性引起了许多生态和进化问题。它们是如何产生的？什么因素有助于稳定假配子孤雌生殖体和它们的精子供体之间的共存（即，“性宿主”）？为什么雄性会把精子浪费在无性的雌性身上？为什么真正的孤雌生殖不能在假配生殖谱系中进化，使它们摆脱对精子捐献者的依赖？假配孤雌生殖是否提供了补偿性的好处，超过了精子依赖的限制？在此，我们考虑了动物中精子依赖性孤雌生殖的一些遗传、生态和地理后果。
Sperm‐dependent (or pseudogamous) forms of parthenogenetic reproduction occur in a wide variety of animals. Inheritance is typically clonal and matroclinous (of female descent), but sperm are needed to initiate normal development. As opposed to true parthenogenesis (i.e., sperm‐independent reproduction), pseudogamous parthenogenetic lineages must coexist with a ‘sperm donor’— e.g., males from a conspecific sexual lineage, conspecific hermaphrodites, or males from a closely related sexual species. Such sperm donors do not contribute genetically to the next generation. The parasitic nature of sperm‐dependent parthenogenesis raises numerous ecological and evolutionary questions. How do they arise? What factors help stabilize coexistence between the pseudogamous parthenogens and their sperm donors (i.e., ‘sexual hosts’)? Why do males waste sperm on the asexual females? Why does true parthenogenesis not evolve in pseudogamous lineages and free them from their dependency on sperm donors? Does pseudogamous parthenogenesis provide compensatory benefits that outweigh the constraints of sperm‐dependence? Herein, we consider some genetic, ecological, and geographical consequences of sperm‐dependent parthenogenesis in animals.
