Expressions for the expectation and variance of the number of segregating sites in samples from an island model of population subdivision are derived. For small samples, an arbitrary number of demes can be accommodated. Results for larger samples are derived under the assumption of an infinite number of demes. However, simulations indicate that the latter results will hold quite well for the finite-island model in many cases. A new estimator of the population migration rate is proposed and is shown to outperform the widely used pairwise method.
推导了来自群体细分岛屿模型样本中分离位点数目的期望和方差的表达式。对于小样本，可以容纳任意数量的deme。在deme数量无限的假设下推导出了大样本的结果。然而，模拟表明，在许多情况下，后一种结果对于有限岛屿模型也能很好地成立。提出了一种新的群体迁移率估计器，结果表明它优于广泛使用的成对方法。
