We provide a new proof of a conjecture of Cox, Katz and Lee for the virtual class of the genus zero moduli of stable maps to $Y$. This in turn yields the expected relationship between Gromov-Witten theories of $Y$ and $X$ which together with Mirror Theorems allows for the calculation of enumerative invariants of $Y$ inside of $X$.This is the version that has been publishedAlgebraic Geometry14N35; 14C17Virtual Class of Zero Loci and Mirror Theoremstext
