Abstract
Most species of the nematode genus Caenorhabditis reproduce through males and females; C. elegans and C. briggsae, however, produce self-fertile hermaphrodites instead of females. These transitions to hermaphroditism evolved convergently through distinct modifications of germline sex determination mechanisms.
摘要
线虫纲秀丽隐杆线虫属的大多数物种通过雄性和雌性进行繁殖；然而，秀丽隐杆线虫和布氏隐杆线虫产生的是能自我繁殖的雌雄同体，而非雌性。这些向雌雄同体的转变是通过生殖系性别决定机制的不同修饰而趋同进化的。
