在文献[4]中，对一个所有等位基因都是选择性中性的，所有突变体都是新的遗传系统建立了一个扩散模型。该模型的状态是基因频率的顺序统计量的向量。这种频率的重新排序是必要的，因为突变的假设。固定等位基因的顺序会导致一个模型，其中基因频率之和在所有正时间都小于1。不幸的是，重新排序使得使用这种方法来研究具有选择的模型几乎是不可能的。
In [4], a diffusion model is constructed for a genetic system in which all alleles are selectively neutral and all mutants are new. The state of this model is the vector of order statistics of the gene frequencies. This reordering of the frequencies is necessary because of the assumption on mutation. Fixing the order of the alleles results in a model in which the sum of the gene frequencies is less than one for all positive time. Unfortunately, reordering makes it virtually impossible to study models with selection using this approach.
