What is Genetic basis of wing morphogenesis in Drosophila : sexual dimorphism and non-allometric effects of shape variation about?

## Background The __Drosophila__ wing represents a particularly appropriate model to investigate the developmental control of phenotypic variation. Previous studies which aimed to identify candidate genes for wing morphology demonstrated that the genetic basis of wing shape variation in __D. melanogaster__ is composed of numerous genetic factors causing small, additive effects. In this study, we analyzed wing shape in males and females from 191 lines of __D. melanogaster__, homozygous for a single __P__-element insertion, using geometric morphometrics techniques. The analysis allowed us to identify known and novel candidate genes that may contribute to the expression of wing shape in each sex separately and to compare them to candidate genes affecting wing size which have been identified previously using the same lines. ## Results Our results indicate that more than 63% of induced mutations affected wing shape in one or both sexes, although only 33% showed significant differences in both males and females. The joint analysis of wing size and shape revealed that only 19% of the __P__-element insertions caused coincident effects on both components of wing form in one or both sexes. F
