- male sterile
X0 animals fail to generate viable cross-progeny.
- drug response variant
Any variation in the characteristic response(s) to drug(s) as defined by control animals.
- long range axon migration variant
Animals exhibit axons with migration behaviors that differ from those observed in control animals after the axons cross a half-way point between opposing neural cords. In C. elegans this point is marked by the lateral seam cells between the ventral and dorsal cords.
