W lineage variant

The descendants of the W precursor cell exhibit any variation in developmental programs compared to their counterparts in control animals.

DAPI staining variant

Animals exhibit variations in the pattern of a chemical nuclear stain which is commonly used in fixed specimens and produces a bright blue label, compared to control. DAPI (4'-6-Diamidino-2-phenylindole) forms fluorescent complexes with natural double-stranded DNA (Wormatlas).
