In humans, more common type of polymorphism is where both alleles are found in both populations but the expression of same kind of allele is based on the various factors between the two population. Environmental factors influence on the expression of same type of allele or different allele in both population. Migration can affect the frequency of expression of same allele when individuals from one population migrate to other population where there is expression of different allele. When all the members of first population carry different allele from other population, the migrated individuals from second population can change the frequency of first population.
