Embryos were injected as described in Figure 1e,f. Partial secondary axes are defined by a morphologically visible ectopic neural tube up to the hindbrain level. Complete axes are defined by the presence of the secondary head structures, including eyes and cement glands. The frequency of secondary axes in uninjected embryos was less than 1%. Data pooled from several independent experiments are shown.
