Migration occurs at a constant rate between two populations of field mice. In one population, 65% of the population are white, in the other population, only 15% are white. What would you expect to happen to the allelic frequencies of these two population over time?

Please provide am explanation of what will happen to the two populations over Time. only looking for generalities, like the ratio will remain the same or you would expect the 15% population to have an increase because of XXXXX.
