Fig. 1. CNS phenotypes of Abl and ama mutants. Embryos from stage
14/15 were stained with mAb BP102 and CNSs were dissected. Representative
examples of the overall phenotype associated with each genotype are shown. (A)
Abl1/Abl4, (B) Abl1,
amaM109/Abl4, (C) Abl1,
Df(3R)ama/Abl4, (D) Abl1,
amaR1/Abl4, (E) Abl1,
amaR1/Abl4, Df(3R)ama, (F)
Abl1, amaM109/Abl4,
Df(3R)ama. Percentages below each panel indicate the
percent of segments with commissure defects; n=total segments scored.
Arrows in B,E show typical examples of segments scored as having defective
commissures.
