Quizplus · Accepted Answer

Directional selection occurs when individuals with traits that are favorable to their environment have higher reproductive success and pass on those traits to their offspring. This results in a change in the population over time through the process of natural selection. Stabilizing selection maintains the status quo by selecting against extremes, the inheritance of acquired characteristics is not a mechanism of evolution, and gene flow is the movement of genes between populations, which can affect their genetic diversity but is not necessarily related to evolution working to effect a change in a population.
