The Weinberg-Salam model is embedded in SU(2/1), thereby considerably
reducing the arbitrariness in SU(2) and U(1) assignments for leptons a
nd quarks. The grading of the matter fields corresponds to their chira
lity. The action of the odd generators of a superalgebra usually invol
ves a change in the statistics of the states, in the representation ca
rrier-space. We explain the interplay between chiralities and statisti
cs.
