Abdominal pigmentation in Drosophila melanogaster is a morphologically simple but highly variable trait that often has adaptive significance. Pigmentation has extensively been studied in Drosophila melanogaster. It has been used as a model for understanding the development and evolution of morphological phenotypes. Pigmentation shows enormous phenotypic variation between species, populations, and individuals, and even within individuals during ontogeny. It gives rise to natural variation, polyphenism and sexual dimorphism. It also varies between species, contributing to species recognition, mate choice, thermoregulation, protection (warning signals), mimicry, and crypsis. Changes in pigmentation are often adaptive and vital to the fitness of the organism. Much is known about the genes that regulate the biochemical synthesis of pigments in D. melanogaster and the genes that control the temporal and spatial distribution of this biosynthesis. Not only is body pigmentation ecologically relevant in Drosophila but it is also a relatively simple and easily measured phenotype to study the genetic architecture of natural variation in complex traits. Each tergite of female D. melanogaster generally has a stripe of dark coloration (melanin) on a lighter tan background (sclerotin). During pre-and post-ecdysis, the epidermal cells underlying the cuticle secrete tyrosine-derived catecholamines into the cuticle for sclerotization and melanisation. The melanin/sclerotin biosynthetic pathway and its underlying genetic basis have been well studied. However, many of the genes known to affect D. melanogaster pigmentation do not form part of this pathway or any parallel pathway. Furthermore, the genes that lead to natural variation in body pigmentation are not necessarily the same genes that are directly involved in the biosynthesis of melanin and sclerotin. By mapping the genetic basis of natural variation in body pigmentation, new genes affecting pigment biosynthesis as well as regulatory regions that determine when and where pigmentation will develop were discovered.
