Fig. 5. Sublamination occurs in lak mutants but is locally perturbed. Confocal images of retinas of line 220 in wild-type and lak background, following IPL sublamination. At 4 and 7 days post-fertilization (dpf), two major sublaminae are observed both in wild type and in lak animals. However, sublamination is perturbed locally in the mutant. Sublaminae are some times absent (1), displaced relative to the adjacent regions (2) or added ectopically (3).
