Migration and Gene Flow
Home > Population Genetics & Statistics > Population Theory > Hardy-Weinberg Principle > Migration and Gene Flow
Migration
Allele frequencies will change if migration occurs into or away from the population. The effect of migration on HWE is dependent on the difference in allele frequencies between the donor and recipient populations.09
Gene Flow
Gene flow is another way to introduce genetic variability to a population. Similar to migration, it occurs when members of one gene pool mate with members of another gene pool, which can lead to an alteration of the allele frequencies.04
