The orientation of the progeny of P7.p mimic those of P5.p and face towards the posterior of the worm, a phenotype referred to as posterior-reversed vulval lineage (P-Rvl).
The descendants of a vulval precursor cell exhibit altered developmental programs compared to their counterparts in control animals. In C. elegans, the VPCs are P3.p-P8.p.
Localization or structural appearance of P-granules is altered compared to control. P-granules are cytoplasmic structures associated with germ nuclei in the C. elegans gonad, and are localized exclusively to germ cells, or germ cell precursors, throughout the life cycle.
