Fig. 3

Loss of Hunchback from post-mitotic neurons does not alter early-born neuronal identity. a Wild type (y w) stage 16 embryo, three segments shown. The U1 neuron is Eve+ Hb+ Zfh2-; one example is circled and enlarged in the inset. b CQ2-gal4 UAS-hb RNAi stage 16 embryo, four segments shown. The U1 neuron is Eve+ Hb- Zfh2-; one example is circled and enlarged in the inset. Note that loss of neuronal Hb does not result in Zfh2 de-repression. c Wild type (y w) second instar larval CNS, four segments shown. The U1 neuron is Eve+ Hb+ Zfh2-; one example is circled and enlarged in the inset. d CQ2-gal4 UAS-hb RNAi second instar larval CNS, four segments shown. The U1 neuron is Eve+ Hb- Zfh2-; one example is circled and enlarged in the inset. Note that loss of neuronal Hb does not result in Zfh2 de-repression. Anterior up, ventral midline at center of each panel, scale bar, 10 μm. e Quantification
