Abstract
Variation at 10 polymorphic isozyme loci was examined for nine populations of quaking aspen (Populustremuloides Michx.) in Minnesota. Mean observed and expected estimates of isozyme heterozygosity were 0.217 and 0.220, respectively, with no significant differences in allele frequencies among populations and no significant deviations from genotype frequencies expected under Hardy–Weinberg equilibrium. These results suggest relatively high levels of gene flow among populations and a mating system involving little inbreeding.Keywords
