WebMigration - "In an evolutionary sense, the movement of alleles between populations" (p. 157). Naturally, the alleles donut move by themselves - they move as organisms disperse from population to population. Note - don't confuse migration in this sense with seasonal migrations, "Gene flow" and "migration" are synonymous. WebGene flow is the movement of genes into or out of a population.
