Fig. 3. LR randomization of habenular laterality. The laterality of lov expression is altered in mutant larvae. (A-D) Approximately half of casanova (cas^ta56), no tail (ntl^b160), floating head (flhⁿ¹) and rescued one-eyed pinhead (oep^m134) homozygotes showed the same lov expression pattern as wild type at 4 d. (E-H) The pattern was reversed in the other half. (I-J) Infrequently, both habenulae showed equivalent levels of expression (and refer to Fig. 4C,F,I). Scale bar: 50 µm. See also Table 1.
