中性等位基因的空间分散是用多型分支过程理论来描述的，在多型分支过程中，类型代表个体可以迁移的殖民地。每个突变个体平均少于一个后代，因此突变种群面临一定的灭绝。给出了在一、二、三维空间中到达特定菌落的个体总数的前两个时刻的表达式。来自果蝇种群的数据被用来显示相同的中性等位基因在广泛分离的地方出现的不可能性。
The spatial dispersion of a neutral allele is described using the theory of multitype branching processes in which the types represent colonies between which individuals can migrate. Each mutant individual averages less than one offspring, so the mutant population faces certain extinction. Expressions are given for the first two moments of the total number of individuals to visit specified colonies in one, two and three dimensions. Data from Drosophila populations are used to show the improbability of the same neutral allele occurring at widely separated localities.
