[Relationship between the reproductive capability of a subdivided population and its genetic structure: computer simulation, the simplest multilocus model].
An original computer model, simulating joint genetic and demographic dynamics of subdivided populations, is proposed. The model accounts for the reverse effect of the genetic structure on the reproductive capability of a population, which is based on a postulated limited set of biallelic loci, controlling variation in an adaptive quantitative trait. The model allows to simulate spreading of the population, originating from a single small colony, which involves genetic and demographic equilibrium (a normal population-genetic process) and reorganization of the genetic structure of the subdivided population upon anthropogenic pressure, associated with a decrease in its reproductive capability (an adverse population-genetic process).
