If you were to block expression of the LIN-3 gene in the early embryonic development of the nematode C.elegans,what would be the most likely result?
A) Cells that normally would differentiate into the anus would remain epidermis.
B) More cells than normal would differentiate into the anus.
C) More cells than normal would become anchor cells.
D) Cells that normally would differentiate into epidermis would become vulval precursors.
E) Cells that normally would differentiate into vulval precursors would become epidermis.

LIN-3 is involved in the signaling pathway that induces vulval precursor cell fate. Blocking its expression would prevent this induction, causing cells that would normally become vulval precursors to remain as epidermis.
