[Locus Adh and adaptation of cn and vg mutants in the experimental populations of Drosophila melanogaster Meig].

Complex study of adaptation and allozyme belonging of alcoholdehydrogenase (ADH) in cn and vg mutants has been carried out in the initial pure lines, in their panmixia populations and in condition of substitution of the mutant genotype by saturating crossings. It was shown that the high level of adaptation of cn mutants and the low level of adaptation of vg mutants was combined with the presence of different ADH allozymes. During the saturating crossings the reliable coadaptation of the genes cn and Adh(S) as well as vg and Adh(F) was detected that confirmes the postulated earlier conception of gene adaptation complexes.
