Scoring of Eve⁺ U motor neurons in Fig. S5C-E for their expression of UAS-reporters and labeling by anti-Hox protein antibodies.

Eve+ U motor neurons in hemisegments within (or adjacent to) the expression patterns of the Antp, Ubx, and Abd-B Hox genes from the brains of three animals were assigned binary scores based on the presence or absence of reporter expression or immunolabeling.
