The models were fitted using maximum log likelihood computed in RMES, and compared using log likelihood ratio tests.
MET, metallicolous; NONMET, non-metallicolous; pop, population; s represents the constrained or unconstrained selfing rate estimated for one population or a group of populations.
The best models are in bold, and the value of underlined estimated selfing rates are provided in Table 7.
