Not all root positions necessarily lead to the conclusion found here concerning the order of origin of floral trimorphism and heteromorphic self-incompatibility.
Given the stability of trimorphism in isolated populations modeled in previous simulations (Eckert and Barrett 1992, fig.
The joint effect of migration rate, population size, and year-to-year survival on the maintenance of trimorphism is illustrated in Figure 4.
