	Please look at the allele reports for the complete phenotype data Ocelli completely absent. Bristles in ocellar area and on top of head irregular and more numerous; postverticals usually absent. Eyes somewhat reduced and body size dwarfed. Phototaxis normal (Benzer, 1967). Viability about 90% wild type. oc and deficiencies for oc show partial dominance to oc+; ocelli placed somewhat far back on head and slight indentation apparent between postvertical bristles (Craymer and Roy, 1980). Ubl/+ enhances dominance of oc; Df(1)RA2/+ exhibit delayed hatch and an oc phenotype; oc2/+ display strong oc phenotype and oc1/oc1 are lethal in combination with Ubl/+ (Mortin and Lefevre, 1981). Lethal alleles (recovered as otd: orthodenticle) die as embryos; all denticles in anterior abdominal s
