Inductive mechanisms in the process of wing vein formation inDrosophila

The mechanisms underlying the formation of veins in the wing ofDrosophila have been studied by means of clonal analysis. To this end the phenotype of vein-suppression mutants (crossveinless, veinlet andradius incompletus), the vein-addition mutantplexus and a mutant causing the appearance of chaetae...
