Summary of genotypes in dichromats and the phenotypes predicted from genetics. See the text in the Discussion for description of category I, II, and III designations. Category IV contains arrays that did not fall into one of the other three categories. Black arrows represent genes encoding L pigment, white arrows represent genes encoding M pigments, arrows that are both black and white with a black arrowhead indicate genes encoding L-class pigments that differ in peak sensitivity compared to the pigment encoded by the black arrow, arrows that are black and white with a white arrowhead indicate genes encoding M-class pigments that differ in peak sensitivity compared to the pigment encoded by the white arrow. The numbers in parenthesis to the left of the arrays indicates the number of subjects with the given array structure. Arrows enclosed within parentheses indicates that subjects varied with regard to the number of genes of the type indicated by the arrow over the range of numbers given in the subscript to the right outside the parentheses.
