摘要：

A model is presented for population fitness and the maintenance of genetic polymorphism. when the environment is subdivided into two ecological patches. Movement of individuals within each geneation is governed by a two-state continuous-time-parameter Markov chain. The outcome of this basic formulation is used to specify the equilibrium gene frequency for two alleles at one locus. The change in gene frequency giving the equilibrium condition is a weighted average of the gene frequency changes appropriate to a coarse-grained and a fine-grained environment. A numerical example is given to illustrate the model. © 1968 N. Rashevsky.
