Abstract
Caenorhabditis elegans primarily reproduces as a hermaphrodite. Independent gene conversion events in mutant obligately outcrossing populations of C. elegans [fog-2(lf)] spontaneously repaired the loss-of-function mutation in the fog-2 locus, thereby reestablishing hermaphroditism as the primary means of reproduction for the populations.
摘要
秀丽隐杆线虫主要以雌雄同体的方式进行繁殖。在秀丽隐杆线虫的突变强制杂交群体[fog-2(lf)]中，独立的基因转换事件自发修复了fog-2基因座中的功能丧失突变，从而重新确立雌雄同体为这些群体的主要繁殖方式。
