爬行动物多父性生殖策略研究进展

动物生殖策略是多种多样的.对一个种群交配体系的调查有助于了解生殖模式的进化情况,并为一些濒危物种的保护计划提供理论依据,同时也为经济养殖动物的人工繁育提供理论支持.多父性( multiple paternity)现象是一种重要的生殖策略,在爬行类动物中普遍存在,并且在主要类群中多父性的水平也比较高,特别是多数有鳞类动物存在多父性现象的窝数可占到总检测窝数的50％以上,这种现象强烈地支持雌性存在混交的进化过程.本文对多父性产生的组织结构、可能机制和多父性的检测手段等进行综述,并对未来的研究方向提出了建议.

Reproductive strategy of multiple paternity in reptiles:A review

Animals have developed a variety of reproductive strategies.To better understand these strategies will not only provide insights into the evolution of animal reproductive mode,but also provide guidelines for more successful conservation managements and captive breeding programs for threatened or endangered species.Multiple paternity is an important reproductive strategy commonly occurred in reptiles,and at higher levels in major groups of reptiles.Especially for the majority of squamates,multiple paternity ...
