Heterochromatin distribution in metaphase chromosomes of three morphologically and karyologically similar members of Drosophila, D. s.sulfurigaster, D. s.bilimbata and D. pallidifrons was studied by the Hoechst 33258 staining method. Comparison showed remarkable uniformity of H-heterochromatin among the three members except for in their Y-chromosomes. On the basis of these observations phylogenetic relationships are discussed.
采用Hoechst 33258染色法研究了果蝇属三个形态学和核型相似的成员，即硫磺果蝇、双翅果蝇和苍白果蝇中期染色体上的异染色质分布。比较表明，除Y染色体外，这三个成员之间的H-异染色质具有显著的一致性。基于这些观察结果，讨论了它们之间的系统发育关系。
