Abstract
We consider a model of the evolution of a population in the presence of epistatic lethal alleles. A model which describes the evolution of lethal and non-lethal alleles based on two-type branching random walks on multidimensional lattices is presented. We study this model in terms of subpopulations of particles generated by a single particle of each type located at every lattice point. The differential equations for the generating functions and factorial moments for the particle subpopulations are obtained. For the first moments we get explicit solutions for cases significant in the genetic context. The asymptotic behaviour for the first moments of particle distribution at lattice points is obtained for a random walk with finite variance of jumps.
