Abstract
Homomorphic multi-locus sporophytically determined self-incompatibilit y systems are much rarer than multi-locus gametophytic systems. This n ote examines some of the possible reasons for this disparity and concl udes that, while each additional locus in a gametophytic system allows increased crossing among related plants as well as a lower mutation r ate to maintain a given level of variability, the same conclusion cann ot be drawn for sporophytic systems.
