head notched

The most anterior portion of the animal contains a V-shaped indentation.

V lineages variant

The descendants of any of the V precursor cells (V1-V6) exhibit altered developmental programs compared to their counterparts in control animals.

D lineage variant

The descendants of the D blastomere exhibit any variation in developmental programs compared to their counterparts in control animals.

male V lineages variant

The descendants of any of the V precursor cells (V1-V6) in male animals, exhibit any variation in developmental programs compared to their counterparts in control animals.

aberrant posteriorly-directed neurite

Any neurite that is extended towards the posterior of the animal from neurons that in wild-type animals make only anterior projections (e.g. D-type neurons in C. elegans).
