We use data taken by the Mark II detector at the SLAC storage ring PEP to study inclusive lepton production in e/sup +/e/sup -/ annihilation at 29 GeV. From fits to the inclusive lepton momentum and transverse-momentum spectra we measure the semileptonic branching ratios for charm and bottom hadrons. We also determine with good precision the mean value of the bottom fragmentation function using both electron and muon samples.
