Using the behavioral phenotypes of a series of 18 mutants falling into five phenotypic classes, Thomas (1990) described the genetic program that controls the cyclic defecation motor program in Caenorhabditis elegans. The first step in each cycle is contraction of the posterior body muscles, followed by contraction of the anterior body muscles. Finally, anal muscles open and expel the intestinal contents. Below is a list of selected mutants (simplified) that cause defects in defecation.
Present a simple schematic that illustrates genetic involvement in C. elegans defecation. Account for the action of the aex gene and speculate on the involvement and placement of the cha gene.
