The yellow (y) gene is a genetic mutations known as Dmel\y within the widely used data base called flybase. This mutation can be easily identified by the atypical yellow pigment observed in the cuticle of the adult flies and the mouth pieces of the larva. The y mutations is comprised of the following phenotypic classes: the mutants that show a complete loss of pigmentation from the cuticle (y-type) while the other mutants show a mosaic pigment pattern with some regions of the cuticle being wild type (y2-type). The role of the yellow gene is diverse and is responsible for changes in behaviour, sex-specific reproductive maturation and epigenetic reprogramming
