A chromosome substitution analysis was carried out in Drosophila melanogaster to elucidate the contribution of the X, II and III chromosomes to female receptivity, and to sexual isolation with its sibling species D. simulans. Two lines from the same base population with extreme phenotypes, the one showing high receptivity and weak isolation and the other showing low receptivity and strong isolation, were used. Genes involved in receptivity were located in chromosome III whereas those affecting sexual isolation were located in all the three chromosomes. These results indicate that the direct relationship between female receptivity and sexual isolation previously detected in D. melanogaster could be because of the occurrence of genes common to the two traits in the chromosome III.
在黑腹果蝇中进行了染色体替代分析，以阐明X染色体、II号染色体和III号染色体对雌性接受性的贡献，以及与同胞物种拟暗果蝇的性隔离情况。使用了来自同一基础种群的具有极端表型的两个品系，一个表现出高接受性和弱隔离，另一个表现出低接受性和强隔离。参与接受性的基因位于III号染色体上，而影响性隔离的基因则位于所有三条染色体上。这些结果表明，先前在黑腹果蝇中检测到的雌性接受性与性隔离之间的直接关系可能是由于III号染色体上这两个性状存在共同基因。
