Abstract

The region 9E1-2 - 10B1-2 of the Drosophila melanogaster X chromosome was analysed under the light (LM) and the electron (EM) microscope using different fixatives and an EM map of the region was constructed. EM analysis revealed 21 bands in the region 9E1-2 - 10B1-2 instead of 36 bands in Bridges' map. This discrepancy mainly results from the fact that 14 bands indicated as "doublets" by Bridges appear as a single bands. No doublets were found in the whole 9B1-2 - 10C1-2 region after fixation of salivary glands in 3% glutaraldehyde, 3% formaldehyde and 3 : 1 ethanol-acetic acid mixture. 45% acetic acid is the only fixative which results in strongly vacuolated appearance of the bands. - The break points of 30 chromosome rearrangements in the region 9E1-2 - 10B1-2 were located under EM or LM within the limits of the EM map of this region.
