| Abstract: | Eight Drosophila melanogaster strains, seven homozygous for Adh
F
alleles and one for an Adh-null mutant, were compared for ADH activity in males and adult mortality on ethanol-supplemented food. The strains differed considerably in these qualities. A positive correlation was found between ADH activity and ld
50. The relevance of this finding is discussed in relation to the differential selection acting on Adh genotypes kept on ethanol-supplemented food. |
