A central assumption used in the genetic fate mapping of anatomical sites responsible for certain mutationally induced abnormalities is that a single pair of bilaterally symmetric sites on the blastoderm gives rise to structures that control the expression of that abnormality. We report a new model that is not so constrained and test its efficacy in the analysis of several mutations that induce behavioral abnormalities.
