Despite extensive prior study, an understanding of the genetic organization of the maroon-like locus (ma-l:1–64.8) has been elusive. A large-scale, three-point fine structure recombination experiment is described, whose results provide documentation for an inescapable argument that maroon-like is a single element rather than a polycistronic system.
