Abstract

Abstract The equations satisfied by the gene frequwncy for various cases of dominance are converted to the type of stochastic differential equation associated with a diffusion process. Using the physical approach to stochastic integrals, the solutions of the corresponding Fokker-Planck equations are obtained. Conditions for quasifixation are investigated and observed frequencies of the gene medionigra of Panaxia dominula are considered in relation to the model of random selection without dominance.
