Some Genetic Features of Population Migration

The differential equation for moving genome of panmictic and inbred populations is found. These equations have allowed find the dependence of the population movement speed on various parameters: average time of a generation alternation, the area of the territory developed by the population for certain time, length of a wave of the moving population and inbreeding factor. The nonlinear differential equation of the third order reflecting natural selection in a population is found. Research of the migrating inbred population at present of natural selection has allowed to fined a condition of the allele frequency preservation at women in Х-chromosomes.
