Homozygotes have eye defects that appear to be limited to the 2o/3o pigment cells of the interommatidial lattice; a small number of excess 2o and 3o pigment cells are seen. The majority of the extra cells are found adjacent to bristles. An ectopic cell positioned between the two 1o pigment cells, called the "cone-contact" cell, is sometimes seen.
