Table 3 Genetic variability at 14 isozyme loci in 20 populations of Pilgerodendron uviferum (standard errors in parentheses). P < 0.95 and P < 0.99 represent the proportion of polymorphic loci with the 0.95 and 0.99 criteria, respectively, A is the mean number of alleles per locus, and HO and HE are the observed and expected heterozygosities, respectively
