N2 - We apply a new method to determine the probability of the uu diquark from p interactions fragmenting as independent quarks. In particular, by assuming that all 's which do not come from Y*+, N*+, or charmed baryons must come from independent fragmentation, we show this probability to be about 50%. We also provide information from n interactions on the fragmentation of ud diquarks into 's, and from this determine the probability of capturing a strange quark from the sea in the target region to be s=0.0510.013, about half the value found in the current region, s=0.120.02. Overall production rates in n and p reactions are (7.0 0.8)% and (7.0 1.2)%, respectively, when cuts of W>4 GeV and xB>0.2 are made on the data.
