Monophenol oxidase (or tyrosinase-A1) activity appears to be absent from extracts from pupae of homozygous lozenge-glossy (lzg/lzg) females and (lzg/♂) males of Drosophila melanogaster. Diphenol oxidase (tyrosinase-A2) activity is less in the mutant extracts than in extracts of wild-type Oregon-R pupae of the same age and sex.
