摘　　要：孤雌生殖是一种不需要雄性参与而直接由未受精卵发育成后代的生殖方式,具有繁殖快、类型多的特点。本文从细胞分裂、遗传、分子进化、环境因素等方面,介绍了不同类群动物中的孤雌生殖特征、发生机理及最新研究成果,为中学生物学教学提供拓展资料。Parthenogenesis is a reproductive method in which offspring are developed directly from unfertilized eggs without male involvement.It is characterized by fast reproduction and multiple types.This article introduces the characteristics and mechanisms of parthenogenesis in different animal groups as well as the latest research findings from cell division,genetics,molecular evolution,and environmental factors,to provide supplementary materials for high school biology teaching.
