Abstract

Contrary to earlier reports, testes of "sex ratio" Drosophila pseudoobscura males have only half as many sperm per bundle as testes of normal males do. This fact, determined from electron micrographs, indicates that the functional pole hypothesis is not applicable to the action of "sex ratio."

摘要

与早期报告相反，“性比”伪暗果蝇雄性的睾丸中，每束精子数量只有正常雄性睾丸的一半。这一通过电子显微镜照片确定的事实表明，功能极假说不适用于“性比”的作用。
