ganglion mother cell GMC1-1a
larval RP2 motor neuron | ectopic
RP2sib neuron
ventral midline of embryo | embryonic stage
The GMC-1 in mutants frequently (in about 2.3% of hemisegments) divide symmetrically to generate two RP2s instead of an RP2 and a sib.
Homozygous embryos exhibit a lack of migrating macrophages along the ventral midline.
