摘要：
A line of Drosophila melanogaster with average male sternopleural bristle number higher than that of females was obtained after many generations of disruptive selection, where males with high bristle score were mated to females with low scores. This abnormal sex-dimorphism did not influence other bristle traits. Dose compensation mechanisms were not involved, and by means of chromosome substitutions it could be shown that both X-linked and autosomal loci contributed to the sex-dimorphism.
