In each generation, 10 percent of the individuals in that population are migrants from another population that has an allele frequency of 0.6. a) Calculate the frequency of A1 in each of the next two generations (generations 1 and 2). b) Is the change in allele frequency in generation 2 greater than, less than, or equal to the change in generation 1?
