If pt is the frequency of an allele in the recipient population in generation t and P is the allelic frequency in a donor population (or the average over several donor populations) and if m is the proportion of the recipient population that is made up of new migrants from the donor population, then the gene frequency in the recipient population in the next generation, pt+1 is the result of mixing 1 m genes from the recipient with m genes from the donor population.
