The thirty‐two possible genic crosses involving two pairs of nonlinked genes were simulated. The anticipated progeny of each cross was analyzed according to each of the seven basic types of epistatic action. A key was devised to facilitate the recognition of genic action since most phenotypic progeny ratios are produced exclusively either by phenotypically similar parents or phenotypically dissimilar parents. Only ratios of 3:1, 2:1, and 1:1 can be produced by both types of parents.
