Difference Between Gene Flow And Colored Birds

Gene flow is the process of alleles moving from one population to another (migration). For example, you have an area with red birds, and in another area you have blue birds. The blue birds migrate to the area with red birds (this shows the gene flow). When the two different colored birds mate, they would have a different types of colored baby birds. A new generation is created by the different color of birds known as genetic diversity.
