Extraction and measurement of the red (pteridine) and brown (ommachrome) eye pigments of Drosophila were carried out basically as described by Ooi et al. (4) except that 20 fly heads (10 male and 10 female) WebThe brick-red eye color of wildtype flies is produced by a mixture of pigments, each pigment is the end product of a series of reactions, each reaction is mediated by an enzyme, and each enzyme is a protein that results from the transcription of a DNA gene. A large number of genes, perhaps 100, are involved in producing eye color in Drosophila.
