在假设不同亚群间迁移率不相同的条件下，利用垫脚石模型和有限岛模型研究了从亚群中随机抽取的两个DNA序列之间的核苷酸差异数，即DNA多态性的期望值。结果表明，在低迁移率的亚群中的DNA多态性的预期量小于高迁移率的亚群。这表明，如果边缘种群的迁移率低于中心种群，则边缘种群的DNA多态性水平往往低于中心种群。
The expected amount of DNA polymorphism, measured in terms of the number of nucleotide differences between the two DNA sequences randomly sampled from subpopulations, was studied by using the stepping-stone model and the finite island model, under the assumption that the migration rate is not the same among different subpopulations. The results obtained indicate that the expected amount of DNA polymorphism in the subpopulation with lower migration rate is smaller than that of higher migration rate. This suggests that marginal populations tend to have lower level of DNA polymorphism than central populations if the migration rate in the marginal populations is lower than that of the central populations.
