[Cytogenetic localization of Acph-1 and Lap-1 genes in virilis group Drosophila].

Gene Acph-1 coding for acid phosphatase was localized on Drosophila virilis chromosome 2 in the region 20A-20E and in D. texana and D. imeretensis homologous regions of the chromosomes 2. Gene Lap-1 coding for leucine aminopeptidase was linked to Acph-1 gene and localized in the 20E-20G region for these Drosophila species. The cytogenetical localization of two genes was determined after analysing recombinant chromosomes by isozymic and cytological methods in the progeny of interspecific hybrids.
