Abstract excerpt
The self-incompatibility (S) locus of flowering plants offers an example of extreme polymorphism maintained by balancing selection. Estimates of recent and long-term effective population size (Ne) were determined for two solanaceous species by examination of S-allele diversity. Estimates of recent Ne in two solanaceous species differed by an order of magnitude, consistent with differences in the species' ecology....
