摘要：

Ethanol and acetic-acid tolerances were studied in a cross between 2 geographic races of Drosophila melanogaster, ie a very sensitive population from equatorial Africa and a resistant French population. Average values in the F1 and F2 were similar and close to the mid-parent value. A clear maternal genotype effect was, however, observed for both traits between reciprocal F1s, and the difference disappeared in the F2. Further investigations demonstrated that for ethanol tolerance, the large difference between the parental strains was not entirely due to differences in their allelic frequencies at the Adh locus. The possible mechanisms of these physiological variations are discussed.
