[Genes, regulating activity of alkaline phosphatase and tyrosine decarboxylase in Drosophila virilis, linked to chromosome 6].

The linkage group of genes controlling alkaline-phosphatase (AP) and tyrosine-decarboxylase (TDC) activities in Drosophila virilis adults was determined. D. virilis strain 160, with all autosomes marked with recessive morphological mutations, was used for the analysis. AP and TDC activities were significantly higher in strain 160 than in strain 147. The analysis of F2 hybrids, which carried one chromosome (one or both homologues) of strain 147 and the rest of strain 160, allowed the assignment of the genes controlling AP and TDC activities in D. virilis adults to chromosome 6.
