Abstract
A cluster of genes corresponding to the early ecdysone stimulated puff 2B of the Drosophila melanogaster X chromosome has been localized using in situ hybridization in eight Drosophila species. Genes ecs, dor and swi from this cluster have been mapped in D. funebris, D. virilis, D. hydei, D. repleta, D. mercatorum and D. paranaensis to the telomeric region of the X chromosome, in D. kanekoi to the distal region, and in D. pseudoobscura, to the proximal region of the X chromosome. It is assumed that organization of this cluster in these species is conserved. In D. hydei, multiple hybridization sites of certain DNA probes from this region were found.
