在关于繁殖和迁移的合理假设下,来自细分种群的样本的系谱由结构化聚结很好地描述,这是金曼的聚结结构化种群的扩展。作为结构化聚结剂的应用的一个例子,在种群结构的对称岛模型中,将来自相同亚群的一对个体的最近共同祖先的时间分布与来自相同总大小的全交配种群的两个个体的时间分布进行比较。对于一个简单的模型的繁殖和迁移,严格的证明,在扩散时间尺度测量时间,祖先的过程收敛(弱)的结构合并,作为子种群的大小趋于无穷大。
The genealogy of a sample from a subdivided population is, under reasonable assumptions about reproduction and migration, well described by the structured coalescent, which is the extension to structured populations of Kingman's coalescent. As an example of an application of the structured coalescent, the distribution of the time since the most recent common ancestor of a pair of individuals from the same subpopulation in a symmetric island model of population structure is compared to that of two individuals from a panmictic population of the same total size. For a simple model for reproduction and migration, a rigorous proof is given that, measuring time in diffusion time-scale, the ancestral process converges (weakly) to the structured coalescent, as the subpopulation sizes tend to infinity.
