I propose that the large mass splitting between the top and bottom quarks is a signature of a class of superstring derived standard-like models. In these models only +2/3 charged quarks obtain a trilevel mass term. Mass terms for the lighter quarks and leptons are obtained from higher order terms in the superpotential. These models contain an anomalous'' U(1) gauge symmetry. Application of the Dine-Seiberg-Witten mechanism cancels the anomaly leaves a cubic level mass term only for the top quark.
