摘要：

Frequency-dependent selection is a fundamental principle of adaptive sex-ratio evolution in all sex ratio theories but has rarely been detected

摘要：

Evolutionary theory predicts that the spread of cytoplasmic sex ratio distorters leads to the evolution of host nuclear suppressors, although ther
