Characterization of a sex-influenced modifier of gene expression and suppressor of position-effect variegation in Drosophila.

Abstract excerpt

Modifier of white (Mow), a dominant transacting gene, has been identified through a mutagenic screen for second-site loci that alter the level of expression of the white eye color locus. Mow reduces the expression of white in most developmental stages, but enhances its expression in the pupal stage, the time at which the major contribution to the adult phenotype is made. Tests with an Alcohol dehydrogenase...
