What would a geneticist say happens when a group of people with blue eyes migrates to an area where people do not have blue eyes, and then both populations interbreed?

Question

Quizplus · Accepted Answer

When two populations interbreed, there is a transfer of genes between the two groups, known as gene flow. As a result, the frequency of the gene for blue eyes may increase or decrease depending on the rate of interbreeding and the selective pressures in the new environment. This process leads to changes in the gene pool of both populations and can contribute to the evolution of new traits over time. Genetic drift, natural selection, and macroevolution may also play a role in this process, but gene flow is the most direct and immediate effect of interbreeding between groups with different gene frequencies.
