| ABSTRACT | Enzyme electrophoresis was used to estimate genetic diversity and population genetic structure of Gleditsia japonica var. koraiensis in Korea. Eleven of the 17 loci (64.7%) showed detectable polymorphism. Genetic diversity (0.247) was higher than average for species with similar life history traits. Analysis of fixation indices, calculated for all polymorphic loci in each population, showed a substantial deficit of heterozygotes relative to Hardy-Weinberg expectations. This deficit is partly associated with inbreeding which is due to consanguineous and selfing mating. The average GST for polymorphic loci was 0.145, indicating that most (85.5%) of the genetic diversity occurred within populations. The indirect estimate of gene flow based on mean GST was moderate (Nm = 1.24). Given limited gene flow, populations are expected to diverge genetically due to drift, the random loss of alleles due to small population size. |
