The amount of change in q is directly proportional to the migration (m); The magnitude of change is also affected by the differences in allelic frequencies of the two populations (qI - qII); What is amount of change when 200 migratory individuals are merge in recipient population size of 1800. Allele frequency of q1 of source and recipient population is .80 and .20 respectively.
