Answer
During the nematode's development, a single anchor cell induces the vulva to form. There are two molecular signals at work: the primary and secondary inducers. Each of the six cells on the ventral surface has three possible fates: a primary vulval precursor cell, a secondary vulval precursor cell, or a simple epidermal cell.
