Q lineage variant

The descendants of Q L or QR cells 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.

loss of left right asymmetry

Bilaterally symmetric cell fail to acquire specific left-right asymmetric properties such as L/R specific cell position, cell death or gene expression.

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).
