The production of electrons by bottom and charm hadrons has been studied in e+e- annihilation at 34.6 GeV center of mass energy. It is observed that the b quark fragmentation function is peaked at large values of the scaling variable z with 〈zb〉 = 0.84+0.15 + 0.15 -0.10 - 0.11. For c quarks 〈zc〉 = 0.57+0.10 + 0.05 -0.09 - 0.06 is observed. A forward-backward charge asymmetry of A = -0.25 ± 0.22 was measured in b production.
