✦ Synopsis
Homomorphic multi-locus sporophytically determined self-incompatibility systems are much rarer than multi-locus gametophytic systems. This note examines some of the possible reasons for this disparity and concludes that, while each additional locus in a gametophytic system allows increased crossing among related plants as well as a lower mutation rate to maintain a given level of variability, the same conclusion cannot be drawn for sporophytic systems.
