Conserved orthologs of these are present in most or all eukaryotes, including Drosophila melanogaster. Some of these genes were originally identified as eye color mutants with decreases in both types of pigments found in the fly eye.

Normal eye colour in Drosophila is red. White eyed Drosophila was one of the first mutations known in Drosophila. Red eye and white eye showed simple dominant recessive relationship. Subsequently, different shades between red and white were recovered.

se: sepia- The eye color of the sepia mutant is sepia, a reddish-brown color. In wild-type flies, ommochromes (brown) and drosopterins (red) give the eyes the typical red color. [64] [65] The drosopterins are made via a pathway that involves a pyrimidodiazepine synthase, [66] which is encoded on chromosome 3L.

The red-brick eye color of a wild-type Drosophila is actually the product of two biochemical pathways—the ommochrome path- way leading to the synthesis of brown pigments and the pteridine pathway that contributes to the red pigments.

Dec 1, 1998 · Analysis of Drosophila eye-colour mutations has made seminal contributions to the fields of genetics and biochemistry. Recent findings suggest that a subset of eye-colour genes is crucial for vesicular transport of proteins to pigment granules, specialized lysosomes of …

Feb 23, 2013 · Two classes of pigments, the brown “ommochromes” and the red “drosopterins”, contribute to the typical eye color phenotype of Drosophila and serve as light-screening pigments (1).

There are two classes of pigments in the eye of Drosophila, brown pigments called ommochromes, which are the products of tryptophane metabolism, and red pigments called pteridines, which are the products of purine metabolism. The wild type eye color is due to a mixture of several different pigments. The wild type eye of
