VPC lineage analysis

Genotype	P3.p	P4.p	P5.p	P6.p	P7.p	P8.p

VPC divisions and adherence to ventral hypodermis were examined at the mid-L3 larval stage, L3 molt, and mid-L4 larval stage. VPC fates from representative hermaphrodites were classified as outlined in the text and as described in Sternberg and Horvitz (1989) and Katz et al. (1995). Abbreviations represent VPC division axes and include L (lateral), T (transverse), O (oblique), N (no division), and D (did not observe). Adherence to the ventral hypodermis is indicated by boldface type (i.e., L). A solid box (unshaded) denotes a primary (1°) fate, a dashed box (unshaded) denotes a secondary (2°) fate, S (syncytial) indicates the tertiary (3°) or nonvulval cell fate, a dashed and shaded box denotes an intermediate fate, and a solid and shaded box denotes a half-vulval fate. Each line represents the vulval lineage from a single hermaphrodite.
