孟德尔遗传在具有不同繁殖结构的群体中的统计结果的比较：泛交配、单亲繁殖、细分为部分隔离的地方菌株、部分隔离的距离。局部种群的部分隔离，即使仅仅是距离的隔离也是重要的，这不仅是物种分裂的可能前兆，而且还导致种群作为一个单一系统更快地进化变化，从而更快地从完全隔离的其他种群中分化出来。一个物种内部的局部分化，或者基于非适应性近亲繁殖效应，或者基于局部选择条件，或者基于两者，允许在一系列多等位基因内和基因组合之间进行试错，从而比在纯粹的Panmictic种群中可能进行的选择过程更有效。
A comparison of the statistical consequences of Mendelian heredity in populations characterized by various breeding structures: panmixia, uniparental reproduction, subdivision into partially isolated local strains, partial isolation by distance. Partial isolation of local populations, even if merely by distance is important, not only as a possible precursor of splitting of the species, but also as leading to more rapid evolutionary change of the population as a single system and thus more rapid differentiation from other populations from which it is completely isolated. Local differentiation within a species, based either on the nonadaptive inbreeding effect or on local conditions of selection or both, permits trial and error both within series of multiple alleles and between gene combinations and thus a more effective process of selection than possible in a purely panmictic population.
