Comparison of mean genetic diversity statistics for self-incompatible (SI) and self-compatible (SC) populations of L. alabamica and L. crassa. Means are shown with standard errors. The number of populations (N) is shown in the first column. Pp = percent polymorphic loci; Total Ap = total number of alleles per populations (including monomorphic loci); APp = mean number of alleles per polymorphic locus; Aep = mean effective number of alleles per locus; Hop = observed heterozygosity; Hep = expected heterozygosity (genetic diversity).
