Abstract
The genetics of two esterase systems in adults of the olive fruit fly Dacus oleae (Gmel.) have been studied by starch gel electrophoresis. Two unlinked autosomal genes, each with multiple alleles, control the synthesis of a number of isozymes. Gene A controls the synthesis of an acetylcholinesterase, and gene B that of a pseudocholinesterase or lipase. Gene B produces hybrid enzyme in heterozygotes for active alleles. In crosses the segregation of seven active and one silent allele in gene A, and of six active and one silent allele in gene B, have been studied. Six more active alleles for gene A and five active alleles of gene B have not been studied in this paper.
